ObjectiveTo study the effect of Taikong Yangxin Pills on the metabolism of simulated weightless rats based on metabolomics and discuss the metabolism mechanism. MethodsIn the simulated space capsule environment on the ground， the rat model of simulated weightlessness was established by the tail suspension method. Rats were randomly grouped as follows： out-of-capsule control， in-capsule control， model， and high （3.0 g·kg^-1） and low （1.5 g·kg^-1） doses of Taikong Yangxin Pills， and they were administrated with corresponding drugs by gavage for 28 days. The serum levels of endogenous metabolites in rats were determined by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF/MS）. The obtained data were processed by principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） to screen for differential metabolites and potential biomarkers. MetaboAnalyst 5.0 was used for pathway enrichment analysis to explain the metabolic regulation mechanism of the drug. ResultsCompared with the out-of-capsule control group， the in-capsule control group showed elevated levels of thirteen metabolites， including 14-hydroxyhexadecanoic acid， linoleic acid， and α-linolenic acid （P<0.05）， which suggested that the space capsule environment mainly affected the metabolism of α-linolenic acid and linoleic acid in the rats. Compared with the in-capsule control group， the model group showed lowered levels of fourteen metabolites， including 4-imidazolone-5-propionic acid， isocitric acid/citric acid， and L-tyrosine （P<0.05）， which were recovered after the treatment with Taikong Yangxin pills （P<0.05）. The pathway enrichment analysis revealed that weightlessness induced by tail suspension and drug intervention mainly involved the phenylalanine， tyrosine， and tryptophan biosynthesis， tyrosine metabolism， histidine metabolism， and citric acid cycle. ConclusionThe simulated space capsule environment and simulated weightlessness induced by tail suspension can both affect the metabolism level of rats. Taikong Yangxin pills can ameliorate the metabolic abnormality in the rat model of weightlessness by regulating various amino acids and energy metabolism-related pathways.

ObjectiveTo observe the clinical efficacy of tonifying kidney and replenishing essence on asthenozoospermia patients with the syndrome of kidney essence deficiency and the effects of this method on the adenosine 5′-monophosphate-activated protein kinase （AMPK）/mammalian target of rapamycin complex 1 （mTORC1） signaling pathway. MethodsSeventy-two eligible asthenozoospermia patients with the syndrome of kidney essence deficiency treated in the Affiliated Hospital of Chengdu University of Traditional Chinese Medicine from February 2023 to January 2024 were selected and randomly assigned into an observation group and a control group， with 36 patients in each group. The observation group received oral administration of Guilu Tianjing capsules， while the control group received oral administration of L-carnitine oral solution. The treatment course lasted for 4 weeks in both groups. The observed indicators included sperm progressive motility rate （PR）， total sperm motility （PR+NP）， percentage of normal mitochondrial membrane potential （MMP）， and traditional Chinese medicine （TCM） symptom scores before and after treatment in both groups. A three-month follow-up was instituted to record the conception status of the patients’ spouses. Additionally， eight patients were randomly selected from the eligible patients in the observation group， and four healthy males with normal semen routine examination results were included as the control group for the determination of protein expression. Western blotting was conducted to assess the expression of AMPK， phosphorylated （p）-AMPK， regulatory-associated protein of mTOR （RAPTOR） and p-RAPTOR， and PTEN-induced putative kinase 1 （PINK1） in sperms from the observation group before and after treatment， as well as in the sperms of the control group. ResultsThe pregnancy rate of spouses in the observation group was 9.09% （3/33）， which was higher than that （3.33%， 1/30） in the control group. The total response rate was 84.8% （28/33） in the observation group and 66.7% （20/30） in the control group， with no statistically significant difference. After treatment， both groups were improved considering PR， PR+NP， MMP， and TCM symptom scores （P<0.01）. Moreover， the observation group exhibited more pronounced decreases in TCM symptom scores than the control group （P<0.05）， while the changes in PR， PR+NP， and MMP showed no statistical significance between groups. Compared with the control group， the asthenozoospermia group exhibited upregulations in phosphorylation levels of AMPK and RAPTOR and protein level of PINK （P<0.01）. The administration of Guilu Tianjing Capsules led to downregulations in the phosphorylation levels of AMPK and RAPTOR and protein level of PINK1 （P<0.01）. However， the protein levels of AMPK and RAPTOR demonstrated no significant difference between before and after treatment. During the study period， neither group of patients exhibited any notable adverse reactions. ConclusionGuilu Tianjing capsules can enhance the sperm motility and percentage of normal mitochondrial membrane potential in asthenozoospermia patients with the syndrome of kidney essence deficiency by downregulating the AMPK/mTORC1 signaling pathway， lowering the protein level of PINK1， and inhibiting excessive activation of mitophagy.

ObjectiveTo observe the clinical effectiveness of point ligation therapy combined with catgut embedment in acupoint for patients with refractory facial paralysis， and to explore the possible mechanisms from the perspective of neurotrophic factors. MethodsTotally 168 patients with intractable facial paralysis were randomly divided into point ligation plus catgut embedment group and electroacupuncture group， with 84 cases in each group. Both groups took methylcobalamin tablets orally， on the basis of which the point ligation plus catgut embedment group gave point ligation therapy at Quanliao （SI 18）， Dicang （ST 4）， Jiache （ST 6）， and catgut embedment in the local acupoints on the affected side combined with the distal acupoints， and the point ligation therapy combined with catgut embedment in acupoint was performed once every 30 days for three treatments； the electroacupuncture group took the same acupoints and gave electroacupuncture， with sparse and dense waves， once every other day. Both groups were treated for 90 days. Before treatment and after 30， 60， 90 and 120 days （follow-up）， patients of both groups were observed for House-Brackmann Facial Nerve Grading （HB） and modified Portmann score； facial nerve electromyography was performed before treatment and after 90 days of treatment to record the wave amplitude and latency of facial nerve motor conduction， and serum brain-derived nerve growth factor （BDNF）， nerve growth factor （NGF）， fibroblast growth factor （FGF2） levels were determined. The clinical effectiveness of both groups after 90 days of treatment was compared， and the adverse events occurred in the course of treatment in all patients were recorded. ResultsAt 30 days， 60 days， 90 days and follow-up visits， the HB grading of patients in both groups improved compared with that before treatment （P＜0.05）； the distribution of the number of patients with HB grading in the point ligation plus catgut embedment group was superior to that in the electroacupuncture group after 60 days and 90 days of treatment and at follow-up visits （P＜0.05）. The maximal amplitude of the facial nerve electromyography in both groups after 90 days of treatment was large， and the latency was shorter when compared with those before treatment （P＜0.05）， and the maximum wave amplitude of the point ligation plus catgut embedment group was higher than that of the electro-acupuncture group， and the latency period was shorter than that of the electro-acupuncture group （P＜0.05）. The modified Portmann scores of the both groups of patients after 30， 60 and 90 days of treatment and follow-up were higher than those before treatment， and the scores of the point ligation plus catgut embedment group were higher than those of the electroacupuncture group （P＜0.05）. Serum BDNF， NGF and FGF2 levels in both groups after 90 days of treatment were higher than before， and the point ligation plus catgut embedment group was significantly higher than the electroacupuncture group （P＜0.05）. The total clinical effective rate of the point ligation plus catgut embedment group （92.68%） was higher than that of the electroacupuncture group （81.01%， P＜0.05）. Adverse reactions occurred in both groups， mainly including local haematoma or subcutaneous bleeding， allergic reaction， severe pain， and needle fainting， all of which disappeared after symptomatic treatment. ConclusionThe point ligation therapy combined with catgut embedment in acupoint for patients with refractory facial paralysis are effective. The therapy improve the facial nerve function， and its mechanism of action may be related to increasing the level of serum neurotrophic factor and thus promoting facial nerve repairment.

This study design of specific identification primers for the ITS2 sequence of F. ussuriensis. The reaction system and conditions were optimized, and PCR-nucleic acid test strips were constructed to realize the visual detection of F. ussuriensis Bark. Through molecular cloning and sequencing technology, we constructed a positive control for F. ussuriensis DNA and formulated quality standards. The established method was evaluated for sensitivity, specificity and reproducibility, and the authenticity of the commercially available samples was identified. Results demonstrated that based on the ITS2 sequences, F. ussuriensis and its mixed forgeries could be distinguished. The PCR products of the authentic F. ussuriensis on test strips showed two bands in the T and C lines, while the pseudo products and negative control showed only one band in the C line, which was consistent with the results of agarose gel electrophoresis. The specificity was 100%, and the sensitivity of the PCR-nucleic acid test strip was up to 0.1 ng·μL^-1, which was 10 times higher than that of the gel electrophoresis assay. 11 out of 16 commercially available samples of F. ussuriensis were qualified, and 5 were unqualified. Collectively, the PCR-nucleic acid test strip method established in this study is specific, rapid, accurate and visualized, which can provide a new technical idea for the detection of F. ussuriensis.
