The efficacy of acupuncture therapies in cervical spondylotic radiculopathy: A network meta-analysis.

Objective: To evaluate the efficacy of acupuncture-related therapy in the Bayesian setting by means of a network Meta-analysis. Methods: Relevant clinical randomized controlled trials(RCTs) of acupuncture-related therapy for Cervical Spondylotic Radiculopathy(CSR) were searched in the Chinese and English databases from the inception to November 13, 2023. Two researchers reviewed the literature, extracted the data, assessed the risk of bias of the included studies independently, and then used Stata14.0 and WinBUGs14 to analyze. Results: There are 28 RCTs in total, of which 2593 patients and 14 acupuncture interventions. Network Meta-analysis revealed that, regarding the VAS scores, Acupoint catgut-embedding, Fu's Subcutaneous Needling and Needle Knife are better than Conventional acupuncture, Electro-acupuncture, Sham needle, Western Medicine, and Electrotherapy; Conventional acupuncture is better than Electrotherapy and Sham needle; Qihuang needle is superior to Sham needle and Electrotherapy; besides, Acupoint catgut-embedding is better than Tuina (Message), Chinese Medicine, Warm needle as well. Regarding the NDI scores, Needle Knife, Warm needle, Fire needle, Long round needle, Acupoint catgut-embedding are better than Conventional acupuncture, Electro-acupuncture, and Cervical traction; Conventional acupuncture is superior to Electro-acupuncture, Cervical traction, Needle Knife and Warm needle; whereas we found Qihuang needle is superior to Acupoint catgut-embedding, besides, Need Knife is superior to Qihuang needle, Long round needle and Acupoint catgut-embedding. In terms of improving the Tanaka Yasuhiro 20-point scale scores(TY), Needle Knife and Qihuang needle are superior to Conventional acupuncture, Warm needle and Electro-acupuncture; moreover, Conventional acupuncture is better than Warm needle. Conclusion: In general, Acupoint catgut-embedding shows the best effect at relieving neck pain, then followed by Fu's Subcutaneous Needling and Needle Knife. Needle Knife is the best intervention in improving the functionality of the cervical spine. Like improving overall clinical performance, Needle Knife is the best treatment. Furthermore, our conclusion still needs to be confirmed by higher-quality documentation. In order to choose the best treatment for patients, clinicians are expected to take into account different clinical features and practical clinical settings with caution while choosing an acupuncture-related therapy in CSR. Key Message: This article aims at selecting the best acupuncture-related treatment for clinicians to help patients in CSR, and the results of this study indicated that Acupoint catgut-embedding shows the best effect in relieving neck pain, Needle Knife shows the best effect in improving the functionality of cervical spine, Needle Knife shows the best effect in treating overall clinical performance.

Electroacupuncture Improves Blood-Brain Barrier and Hippocampal Neuroinflammation in SAMP8 Mice by Inhibiting HMGB1/TLR4 and RAGE/NADPH Signaling Pathways.

OBJECTIVE: To investigate the molecular mechanisms underlying the beneficial effect of electroacupuncture (EA) in experimental models of Alzheimer's disease (AD) in vivo. METHODS: Senescence-accelerated mouse prone 8 (SAMP8) mice were used as AD models and received EA at Yingxiang (LI 20, bilateral) and Yintang (GV 29) points for 20 days. For certain experiments, SAMP8 mice were injected intravenously with human fibrin (2 mg). The Morris water maze test was used to assess cognitive and memory abilities. The changes of tight junctions of blood-brain barrier (BBB) in mice were observed by transmission electron microscope. The expressions of fibrin, amyloid- ß (Aß), and ionized calcium-binding adapter molecule 1 (IBa-1) in mouse hippocampus (CA1/CA3) were detected by reverse transcription-quantitative polymerase chain reaction (qRT-PCR), Western blot or immunohistochemical staining. The expression of fibrin in mouse plasma was detected by enzyme-linked immunosorbent assay. The expressions of tight junction proteins zonula occludens-1 and claudin-5 in hippocampus were detected by qRT-PCR and immunofluorescence staining. Apoptosis of hippocampal neurons was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining. RESULTS: Fibrin was time-dependently deposited in the hippocampus of SAMP8 mice and this was inhibited by EA treatment (P<0.05 or P<0.01). Furthermore, EA treatment suppressed the accumulation of Aß in the hippocampus of SAMP8 mice (P<0.01), which was reversed by fibrin injection (P<0.05 or P<0.01). EA improved SAMP8 mice cognitive impairment and BBB permeability (P<0.05 or P<0.01). Moreover, EA decreased reactive oxygen species levels and neuroinflammation in the hippocampus of SAMP8 mice, which was reversed by fibrin injection (P<0.05 or P<0.01). Mechanistically, EA inhibited the promoting effect of fibrin on the high mobility group box protein 1 (HMGB1)/toll-like receptor 4 (TLR4) and receptor for advanced glycation end products (RAGE)/nicotinamide adenine dinucleotide phosphate (NADPH) signaling pathways (P<0.01). CONCLUSION: EA may potentially improve cognitive impairment in AD via inhibition of fibrin/A ß deposition and deactivation of the HMGB1/TLR4 and RAGE/NADPH signaling pathways.

Posterior reversible encephalopathy syndrome associated with use of anlotinib to treat squamous cell carcinoma of the cervix: case report and literature review.

Background: Posterior reversible encephalopathy syndrome (PRES), a neurological disorder with an unknown aetiology, is characterised by visual impairment, headache, vomiting, seizures, and transient alterations in consciousness. Case report: We present the case of a 49-year-old woman with advanced cervical carcinoma who received second-line therapy with oral anlotinib (12 mg, days 1-14, every 21 days) and injectable tislelizumab (200 mg, day 1, every 21 days). After 7 days of anlotinib administration, she began experiencing symptoms suggestive of PRES and was diagnosed on day 11. Interruption of anlotinib and supportive treatment led to recovery of her binocular vision. The Naranjo score (+5) graded the causality of this reaction as probable, suggesting the possibility that the event may have been an adverse reaction to anlotinib. Ethics: This case report was approved by the Ethics Committee of the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine (Reference no. K-2023-068, 2023/06/09). Informed consent was obtained from the patient and her family.

Doxycycline-moxifloxacin sequential therapy for Mycoplasma genitalium urethritis/cervicitis: a clinical observation / 中华皮肤科杂志

Objective:To investigate outcomes and safety of doxycycline-moxifloxacin sequential regimen in the treatment of Mycoplasma genitalium urethritis/cervicitis. Methods:From June 2019 to December 2020, patients with Mycoplasma genitalium urethritis/cervicitis confirmed by nucleic acid amplification testing were successively recruited at Department of Sexually Transmitted Diseases, Hospital of Dermatology, Chinese Academy of Medical Sciences, and received sequential therapy with oral doxycycline for 7 days followed by oral moxifloxacin for 7 days. Clinical and/or etiological assessment was conducted 2 to 3 weeks after the end of treatment. Fisher′s exact test was used to analyze factors influencing the treatment outcome. Results:Totally, 36 eligible subjects were enrolled, including 30 males and 6 females. Among them, 18 (50%) patients completed post-treatment etiological assessment, which showed that 12 achieved microbiological cure, and treatment failures occurred in 6; another 18 patients achieved clinical cure. The overall response rate to doxycycline-moxifloacin sequential therapy was 83.3% (30/36, 95% confidence interval[ CI]: 70.5%, 96.1%) . The treatment outcome showed no significant association with the patients′ age, gender, marital status, number of sexual partners in the past 1 month, history of sexually transmitted diseases, history of antibiotic use in the past 1 month, or co-infections (all P > 0.05) . Conclusion:The efficacy of doxycycline-moxifloacin sequential regimen is limited in the treatment of Mycoplasma genitalium infections in Nanjing area, and clinicians should be alerted to the possibility of treatment failure in clinical practice.

[Analysis of transcriptome differences in two leaf-type cultivars of Aconitum carmichaelii].

According to the major differences of agricultural characters among various Aconitum carmichaelii cultivars, the lateral roots of Ai-leaf and Dahua-leaf A.carmichaelii plants were selected as the research objects. And the Illumina Hiseq high-throughput platform was used for transcriptome sequencing, assembly and annotation. We mostly focused the activity differential transcripts, metabolism pathways and enrichment functions. The results showed that a total of 52.23 Gb nucleotide bases were obtained from 6 A.carmichaelii transcriptome databases, with 52 471 unigenes and 28 765 matched annotation. There were 1 052 transcripts of the two kinds of A.carmichaelii with a difference of more than 2 times, 808 of which were annotated. Through GO and COG analysis, they were found to mainly concentrate in metabolic processes, cell processes, catalytic processes and transport processes, connections and other functions. KEGG analysis showed that 262 DEGs were enriched in 78 metabolic pathways, such as starch and sucrose metabolism, plant hormone signaling, carbon compounded transport etc. It was implied that many genes in Dahua-leaf A.carmichaelii regulated the conversion of starch to small molecules such as sucrose, glucose and maltose, while some other genes regulated the accumulation of amino acids, which may be the important biological principles for the formation of the differences between the quality and disease resistance of two leaf types of A.carmichaelii. This study will provide reference datas for A.carmichaelii breeding research.

Identification of a second follistatin gene in grass carp (Ctenopharyngodon idellus) and its regulatory function in myogenesis during embryogenesis.

Follistatin can antagonize the function of myostatin as a competitive binding protein and promote muscle growth in vivo. Here, we report the isolation and characterization of a second follistatin gene fst2 in grass carp (Ctenopharyngodon idellus). The grass carp fst2 cDNA was 1,376 bp in length, with an open reading frame (ORF) encoding 350 amino acid residues. A relatively low sequence identity of 78% was found between grass carp Fst2 and its paralog Fst1. Sequence and phylogenetic analyses suggest that the grass carp fst2 originated from fish-specific gene duplication. In adult fish, fst2 mRNA expression was observed in most tissues but was strongly expressed in the eyes, muscles, skin and ovary. Grass carp fst2 mRNA could be detected as early as 16 h post-fertilization (hpf), while fst1 mRNA was detected throughout embryogenesis. Using in situ hybridization, fst2 transcripts were detected in the anterior somites at 24 hpf and in the brain and posterior somites at 36 hpf. Meanwhile, fst1 mRNA was transcribed mainly in the optic vesicle and at the cephalic mesoderm at 12 hpf, in the eyes, cephalic mesoderm and at the lateral edge of most somites at 24 hpf, and mainly in the brain at 36 hpf. Furthermore, overexpression of fst2 mRNA markedly affected the formation of the embryonic midline and somite structures. Based on comparisons with fst1, our findings suggest that fst2 retained the ancestral functions of regulating muscle development and growth during embryogenesis in grass carp.

Leucine-Aspartic Acid-Valine sequence as targeting ligand and drug carrier for doxorubicin delivery to melanoma cells: in vitro cellular uptake and cytotoxicity studies.

PURPOSE: To study the feasibility of Leucine-Aspartic Acid-Valine (LDV) as targeting ligand and drug carrier for targeted delivery to integrin alpha(4)beta(1) over-expressing cancer cells. METHODS: Poly(L,D,V) was randomly copolymerized using N-carboxyanhydrides of leucine, beta-benzyl-aspartic acid, and valine. Oligo(LDV), consisting of 2-6 LDV units, were synthesized by solid phase protein synthesis (SPPS) method. Binding of Leu-Asp-Val, Val-Asp-Leu, and Leu-Asn-Val, and internalization of FITC labeled LDV by wild-type and integrin alpha(4) knock-down A375 cells were studied. Cytotoxicity of poly(L,D,V)-Dox, oligo(LDV)-Dox, and doxorubicin (Dox) was also determined on wild-type, integrin alpha(4) knock-down A375 cells, and normal human epithelial keratinocytes (NHEK). RESULTS: LDV was essential for the specific binding and internalization by cells expressing integrin alpha(4)beta(1). Cytotoxicity of poly(L,D,V)-Dox and oligo(LDV)-Dox was integrin alpha(4)-dependent, while free Dox did not show this differential effect. No observable cytotoxicity trend was found when increasing LDV repeating unit. Poly(L,D,V) was relatively more effective than oligo(LDV) for the delivery of Dox to A375. CONCLUSION: LDV containing moieties bind specifically to integrin alpha(4)beta(1) expressing cancer cells. The binding, internalization, and cytotoxicity depend on the level of integrin alpha(4)beta(1) expression. Poly(L,D,V) and oligo(LDV) were both effective in the in vitro targeted delivery of Dox to integrin alpha(4)beta(1) over-expressing A375 cells.

[Bovine jugular venous conduit treated with the polyepoxy compound].

OBJECTIVE: To determine the feasibility whether the bovine jugular venous conduit (BJVC) can be fixed with polyepoxy compound (PC). METHODS: Twenty-four BJVCs were divided into 3 groups and fixed with polyepoxy compound (PC group, n = 8), glutaraldehyde (GA group, n = 8), and unfixed group (Control group, n = 8), respectively. The morphologic and mechanical properties of BJVCs in the 3 groups, including thickness, diameter, moisture content, denaturation temperature, tensile strength, elongation at break, and fixation index were measured. The rat subcutaneous model for the assessment of tissue calcification was used. The calcium content in bovine jugular vein patches and valves was determined by flame atomic absorption spectrophotometer. RESULTS: There was no difference in the wall thickness, diameter, and tissue water content between PC and the control group, but significant difference was found between GA and PC groups. The mechanical properties of PC group and GA group were not significantly different, but they were better than those of the control group. GA-fixed BJVC samples showed clear calcification, while PC fixed BJVC were calcified significantly less. CONCLUSION: PC is an effective and suitable choice for the treatment of BJVC since it can effectively preserve the structure and the anti-reflow function of valves in bovine jugular vein and it has better anti-calcification properties.

Studies on acyclovir-dextran conjugate: synthesis and pharmacokinetics.

Acyclovir is an antivirus drug which has a good in vitro activity against hepatitis B virus. But because of the low solubility and low distribution in liver, the clinical application of acyclovir in hepatitis B was limited. To increase the solubility and the distribution in liver, acyclovir-dextran conjugate was synthesized by formation of Schiff's base. The solubility of obtained conjugate was 12 times greater than free acyclovir. Acyclovir will be slowly released from the obtained conjugate in pH 7.4 phosphate buffer solution (PBS) at 37 degrees C with a rate constant of 0.0035 hr(-1). Pharmacokinetic studies of acyclovir and acyclovir-dextran conjugate were conducted in mice by i.v. administration. Acyclovir concentrations in plasma, liver and kidney were determined by HPLC method. Relatively higher distribution of acyclovir in liver was observed when i.v. acyclovir-dextran conjugate as compared with i.v. free acyclovir. The results of pharmacokinetic studies indicated that acyclovir-dextran conjugate will be a good candidate to treat hepatitis B.
