OBJECTIVE: To observe the clinical efficacy of Daoqi (directing qi flowing) acupuncture technique in Huangdi Neijing (Yellow Emperor's Inner Classic) for moderate-to-severe obstructive sleep apnea-hypopnea syndrome (OSAHS). METHODS: Sixty patients with moderate-to-severe OSAHS were randomly divided into a Daoqi acupuncture group (30 cases) and a conventional acupuncture group (30 cases, 1 case dropped out). In the Daoqi acupuncture group, Daoqi acupuncture technique in Huangdi Neijing was applied at Shanglianquan (Extra), Fengfu (GV16), and bilateral Lieque (LU7), Zhaohai (KI6); in the conventional acupuncture group, conventional acupuncture was applied at Shanglianquan (Extra), Fengfu (GV16), Yamen (GV15), and bilateral Lieque (LU7), Zhaohai (KI6), Zusanli (ST36), Fenglong (ST40). The treatment was adopted once every other day, 3 times a week, 4 weeks as one course and 3 courses were required totally in both groups. Before and after treatment, the polysomnography (PSG) indexes [apnea-hypopnea index (AHI), hypopnea index (HI), apnea index (AI), longest apnea duration, lowest nocturnal SaO₂ (LSaO₂)], and scores of Epworth sleepiness scale (ESS), Pittsburgh sleep quality index (PSQI), World Health Organization quality of life-BREF (WHOQOL-BREF) were observed, and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: After treatment, the AHI, HI, AI and longest apnea duration were reduced compared with those before treatment in the two groups (P<0.01), the LSaO₂ was increased in the Daoqi acupuncture group (P<0.01); in the Daoqi acupuncture group, the AHI, HI, AI and longest apnea duration were lower than those in the conventional acupuncture group (P<0.05), and the LSaO₂ was higher than that in the conventional acupuncture group (P<0.05). After treatment, the ESS and PSQI scores were decreased compared with those before treatment (P<0.01), while the WHOQOL-BREF scores were increased compared with those before treatment (P<0.01) in the two groups; in the Daoqi acupuncture group, the ESS and PSQI scores were lower than those in the conventional acupuncture group (P<0.05, P<0.01), and the WHOQOL-BREF score was higher than that in the conventional acupuncture group (P<0.05). The total effective rate was 93.3% (28/30) in the Daoqi acupuncture group, which was higher than 82.8% (24/29) in the conventional acupuncture group (P<0.01). CONCLUSION Daoqi acupuncture technique in Huangdi Neijing can effectively treat moderate-to-severe OSAHS patients, improve the clinical symptoms and quality of life, and has the advantages i.e. simpler acupoints selection and gentler stimulation.

Perimenopause raises the risk and incidence of depression, whereas the underlying molecular mechanism remains unclear. Disturbed glucose regulation has been widely documented in depressive disorders, which renders the brain susceptible to various stresses such as estrogen depletion. However, whether and how glucose dysfunction regulates depression-like behaviors and neuronal damage in perimenopausal transition remains unexplored. Here, a prominent depressive phenotype was found in perimenopausal mice induced by the ovarian toxin 4-vinylcyclohexene diepoxide (VCD). The VCD depression susceptible group (VCD^SS) and the VCD depression resilient group (VCD^RES) were determined using a ROC-based behavioral screening approach. We found that the hippocampus, a crucial region linked to depression, had hyperglycemia and mitochondrial abnormalities. Interestingly, oral administration of the SGLT2 inhibitor empagliflozin (EMPA) and intrahippocampal glucose infusion suggest a close relationship between hyperglycemia in the hippocampus and the susceptibility to depression. We verified that cytochrome c oxidase 7c (COX7C) downregulation is a potential cause of the high glucose-induced neuronal injury using proteomic screening and biochemical validations. High glucose causes COX7C to be ubiquitinated in a S-phase kinase associated protein 1 (SKP1)-dependent manner. According to these results, SKP1/COX7C represents a unique therapeutic target and a novel molecular route for treating perimenopausal depression.

Abstract Migraine is a widespread neurovascular disorder, the pathogenesis of which is closely linked to the release of calcitonin gene-related peptide(CGRP), leading to a significant impairment in patients′ quality of life. CGRP receptor antagonists exert their therapeutic effect by inhibiting the interaction between CGRP and its receptors, thereby preventing migraine attacks. Currently, several agents, including Rimegepant and Ubrogepant, have either received approval from the U. S. Food and Drug Administration or are in advanced stages of clinical trials.These drugs offer multiple advantages, such as the absence of vasoconstrictive effects, a rapid onset of action, and minimal interference with the immune system. Nevertheless, further investigation is necessary to assess their longterm safety, the potential emergence of drug resistance, and the development of individualized treatment protocols.Moreover, the integration of these novel therapies with existing treatment strategies remains a critical area for future research. This review aims to summarize recent national and international scientific advancements to establish a theoretical basis for the application of precision medicine in migraine management.

The bacterial ATP-competitive GyrB/ParE subunits of type II topoisomerase are important anti-bacterial targets to treat super drug-resistant bacterial infections. Herein we discovered novel pyrrolamide-type GyrB/ParE inhibitors based on the structural modifications of the candidate AZD5099 that was withdrawn from the clinical trials due to safety liabilities such as mitochondrial toxicity. The hydroxyisopropyl pyridazine compound 28 had a significant inhibitory effect on Gyrase (GyrB, IC₅₀ = 49 nmol/L) and a modest inhibitory effect on Topo IV (ParE, IC₅₀ = 1.513 μmol/L) of Staphylococcus aureus. It also had significant antibacterial activities on susceptible and resistant Gram-positive bacteria with a minimum inhibitory concentration (MIC) of less than 0.03 μg/mL, which showed a time-dependent bactericidal effect and low frequencies of spontaneous resistance against S. aureus. Compound 28 had better protective effects than the positive control drugs such as DS-2969 ( 5) and AZD5099 ( 6) in mouse models of sepsis induced by methicillin-resistant Staphylococcus aureus (MRSA) infection. It also showed better bactericidal activities than clinically used vancomycin in the mouse thigh MRSA infection models. Moreover, compound 28 has much lower mitochondrial toxicity than AZD5099 ( 6) as well as excellent therapeutic indexes and pharmacokinetic properties. At present, compound 28 has been evaluated as a pre-clinical drug candidate for the treatment of drug-resistant Gram-positive bacterial infection. On the other hand, compound 28 also has good inhibitory activities against stubborn Gram-negative bacteria such as Escherichia coli (MIC = 1 μg/mL), which is comparable with the most potent pyrrolamide-type GyrB/ParE inhibitors reported recently. In addition, the structure-activity relationships of the compounds were also studied.

Using chemoproteomic techniques, we first identified EIF2AK2, eEF1A1, PRDX3 and VPS4B as direct targets of berberine (BBR) for its synergistically anti-inflammatory effects. Of them, BBR has the strongest affinity with EIF2AK2 via two ionic bonds, and regulates several key inflammatory pathways through EIF2AK2, indicating the dominant role of EIF2AK2. Also, BBR could subtly inhibit the dimerization of EIF2AK2, rather than its enzyme activity, to selectively modulate its downstream pathways including JNK, NF-κB, AKT and NLRP3, with an advantage of good safety profile. In EIF2AK2 gene knockdown mice, the inhibitory IL-1β, IL-6, IL-18 and TNF-α secretion of BBR was obviously attenuated, confirming an EIF2AK2-dependent anti-inflammatory efficacy. The results highlight the BBR's network mechanism on anti-inflammatory effects in which EIF2AK2 is a key target, and inhibition of EIF2AK2 dimerization has a potential to be a therapeutic strategy against inflammation-related disorders.

Objective:To explore the epidemiological characteristics, risk factors, preventions and treatments of recent human parvovirus B19 (HPV-B19) infections in recipients of renal transplantation (RT).Methods:From May 2020 to June 2021, retrospective review was conducted for epidemiological characteristics, treatment protocols, preventions and outcomes of HPV-B19 infected recipients after RT.Risk factors were analyzed using uninfected recipients after RT in the same period as controls.And 78 recipients who were not infected after RT with similar operation time were used as a control group for risk factor analysis.The infection rates of the four liver transplant recipients infected with HPV-B19 during the same period were calculated and compared with those of the kidney transplant recipients.Chi-square test and Fisher's exact test were used for statistical analysis.Results:During the observation period, HPV-B19 infection occurred in 39/368 recipients after RT with an overall infection rate of 10.60%(39/368). In terms of clinical symptoms, all 39 recipients presented with pure red cell aplasia (PRCA). In terms of season of infection, HPV-B19 infections occurred predominantly in autumn and winter [74.3% (29/39) of infections in autumn and winter, including 48.7% (19/39) in autumn]. Comparing the infection rates of different transplant recipients, 4 out of 123 liver transplant recipients were infected with HPV-B19 during the same period.The rate of infection was lower in liver transplant recipients than in RT counterparts (3.25% vs.10.60%, χ2=6.225, P=0.013). Analysis of OR values showed that transfusion of blood products was a risk factor for recent postoperative infection ( χ2=4.806, P=0.028, OR=2.418, 95% CI=1.088-5.373). Conclusions:HPV-B19 infection in renal transplant patients is mainly manifested as PRCA and is more likely than in liver transplant patients.Autumn and winter may be susceptible seasons for HPV-B19 and protection should be increased to prevent infection.Transfusion of blood products is a risk factor for recent HPV-B19 infection after RT, therefore donors should be routinely examined and it is imperative to test the safety of blood products in patients after RT.Thus HPV-B19 infection is well-controlled so that further spread may be prevented to avoid an epidemic outbreak.

Objective:To observe the safety and efficacy of early conversion into a simplified once-daily immunosuppressive regimen of sirolimus plus low-dose extended-release tacrolimus in kidney transplant recipients.Methods:From April 2019 to August 2020, clinical data were collected from 44 recipients (22 pairs) of kidney transplantation. Two kidneys from the same donor were randomly divided into observed and control groups. The immunosuppressive regimen of two groups was the same within 1 month post-transplantation, i. e. tacrolimus plus mycophenolatemofetil (or mycophenolate sodium) and prednisone. Then the immunosuppressive regimen of observed group was switched into a simplified once-daily regimen of sirolimus plus low-dose extended-release tacrolimus and prednisone while control group remained unchanged. The changes of graft function, proteinuria and the incidence of related adverse events were recorded.Results:No inter-group difference existed in serum level of creatinine at Month 1 post-transplantation (163.40±51.57 vs 166.10±49.48 μmol/L). After regimen conversion, serum level of creatinine was slightly lower in observed group than that in control group at Months 3 and 6 post-transplantation (130.10±30.10 vs 134.90±28.97, 121.50±24.96 vs 136.30±27.06). However, there was no statistic difference. The 24-hour urinary total trace protein was slightly higher in observed group than that in control group (331.20±84.21 vs 279.50±80.91 and 209.60±66.02 vs 179.50±37.60 mg/24 h) at Months 3 and 6 post-transplantation. However, there was no statistic difference. No inter-group difference existed in the incidence of drug side effects or other adverse events.Conclusions:In kidney transplant recipients at Month 1 post-transplantation, a conversion of immunosuppressive regimen into a simplified once-daily of sirolimus plus low-dose extended-release tacrolimus can significantly boost patient compliance without an elevated risk of drug side effects or adverse events and offer an advantage of reducing nephrotoxicity.

Objective:To investigate the clinical, laboratory and imaging evaluation, treatment and prognosis of patients with idiopathic hypertrophic pachymeningitis (IHP) with ophthalmic manifestations as the first symptom.Methods:A retrospective case analysis. Eight patients displaying symptoms of IHP were recruited from the Neuro-ophthalmology Department in the First Medical Center of Chinese PLA General Hospital from January 2016 to April 2019 were inculed in this study. There were 6 males and 2 females, aged from 11 to 65 years, with an average age of 48.00±19.08 years. The course of disease ranged from 30 days to 7.5 years, with an average course of 17.00±30.08 months. The age, symptoms and signs of all patients were recorded. All patients underwent ophthalmic examination, orbit or brain MRI or CT examinations, blood routine examination, biochemistry, tumor markers, immunity, hepatitis B, syphilis, HIV, thyroid function and other laboratory tests, and lumbar puncture was performed to measure the cerebrospinal fluid (CSF) pressure and indicators. The clinical manifestations, orbital or brain MRI imaging and laboratory examination characteristics were summarized. Treatment and prognosis were also observed.Results:In total of 8 patients, visual loss was presented in 6 patients, visual loss and diplopia were presented in 1 patient, and diplopia was presented in 1patient. Binocular involvement in 7 patients and monocular involvement in 1 patient. Other symptoms including headache and hear loss and so on. Optic disc edema in 1 eye and optic disc pallor in 6 eyes were reviewed by fundus examination. The laboratory examination showed that the angiotensin converting enzyme abnormal in 4 patients, the anti-thyroid peroxidase antibody abnormal in 3 patients and immunoantibodies positive in 3 patients. CSF measurements showed that the protein level elevated in all patients. Orbit and/or brain MRI and CT examination showed that optic nerve involvement in 6 patients, oculomotor nerve involvement in 1 patient, and cavernous sinus region involvement in 2 patients. Glucocorticoid was effective in all patients, and the visual acuity significantly improved in 4 patients, the diplopia was completely resolved in 2 patients, and the disease modifying therapy (DMT) was combined to prevent recurrence in 7 patients. No recurrence was observed in an average follow-up time of 26.63±16.55 months.Conclusions:IHP patients may be first visit an ophthalmologist due to vision loss in bilateral eyes simultaneous or sequentially. IHP patients are often associated with headache and other cranial nerve paralysis symptoms. Definitive diagnosis of IHP depends on imaging examination. Glucocorticoid treatment is effective in early phase, but it is tendency to progress and relapse, suggesting combined with DMT as early as possible.

With the integration of acupuncture into Qatar’s national medical system in 2016, TCM has made great progress in the State of Qatar. At the same time, the launch of the Qatar National Vision 2030 and the Belt and Road Initiative has provided a good opportunity for TCM development there. At present, the state of Qatar lacks local education and policy support for TCM development and there exists competition from other traditional medicine. However, the domestic investment environment is stable. TCM development in Qatar has to focus on expanding the Chinese medicine market, promoting scientific research cooperation, encouraging herbal medicine enterprises to develop planting industry, and striving for preferential policies to develop TCM service trade.

Transient ischemic attack (TIA) is a high-risk signal of acute ischemic cerebrovascular diseases, indicates a significant increase in the risk of ischemic stroke, especially within 7 days.Risk assessment and stratification are important in patients with TIA.A variety of simple prediction scales were developed based on the risk factors for stroke in patients with TIA, such as the California scale, ABCD scale, and ABCD2 scale.Among them, the ABCD scale score is used most commonly, but as its application becomes more and more common, the defects of this scale are also increasingly apparent.In recent years, some derived scales of ABCD score were introduced in order to improve the sensitivity and specificity of prediction.This article reviews the evolution, contents, characteristics, and predictive value of the ABCD score and its derived scales in the prediction of stroke risk in patients with TIA.
