Objective:To explore whether antioxidant coenzyme Q10 (CoQ10) is involved in the regulation of renal injury induced by diquat poisoning (DQ) in rats through anti-oxidative stress and inhibition of interleukin (IL)-17 and nuclear factor kappa-B (NF-κB) signaling pathway, and whether this mechanism is related to alleviating mitochondrial dysfunction.Methods:The expressions of NF-κB inhibitory protein α (IKB-α), phosphorylated nuclear factor κB (P-NF-κB), JNK-related leucine zipper protein (JLP) and neuroprotective protein PTEN-induced putative kinase 1(PINK1) pathway proteins were detected in vivo and in vitro. Biochemical detection of renal injury markers and inflammatory cytokines: serum urea nitrogen (BUN), serum creatinine (Cr), Cystatin C (CysC), renal injury molecule 1, Malondialdehyde, Supemxidedismutase (SOD), neutrophil gelatinase-associated lipocalin (NGAL), etc. Renal pathology HE staining was used to observe the degree of renal injury and pathological score under light microscope. The expression of reactive oxygen species (ROS) was detected by immunofluorescence. CCK-8 experiment was used to observe the level of cell proliferation after administration.Results:In vivo experiment, the indexes of renal function injury (Cr, BUN, CysC, NAGL, KIM-1) in plasma and kidney samples were significantly increased after 72 h of exposure in DQ group, and there were significant histopathological changes and pathological scores increased. In vitro experiment HK-2 cells were exposed to DQ for 48 h, and the cell viability decreased by half. After exposure to DQ, serum SOD decreased, MDA increased, and the immunofluorescence value of ROS in renal tissue increased. Intervention with CoQ10 can alleviate the pathological damage induced by DQ in rats, enhance the vitality of HK-2 cells, alleviate renal injury and reduce the level of oxidative stress. In addition, the expression of pro-inflammatory cytokines (IL-6, TNF-α and IL-17) increased in DQ group in vivo, the expression of P-NF-κBp65 protein in DQ group in vivo and HK-2 cell DQ group in vitro increased significantly, the expression of mitochondrial dysfunction index PINK1 protein increased significantly, and the expression of JLP protein and IκB-α protein decreased significantly. After intervention with CoQ10, the expression of P-NF-κBp65 protein and PINK1 can be decreased, while the expression of IκB-α protein can be increased and the degradation of JLP could be alleviated, and CoQ10 could improve the mitochondrial dysfunction after DQ poisoning.Conclusions:CoQ10 can alleviate the kidney injury induced by DQ poisoning in rats, and its mechanism may be related to the fact that CoQ10 regulates the expression of IL-17 and NF-κB signaling pathway through anti-oxidative stress, and further improves mitochondrial dysfunction.

Objective To analyze medication patterns and the targets and pathways of core drug combinations in treatment of palpitation.Methods The prescriptions of Li Yaping for treatment of palpitation from March 2023 to March 2024 were collected,and frequency counts of drugs'nature and flavour,channel tropism,and efficacy were performed.Apriori algorithm,association rules,and clustering analysis were carried out using SPSS Modeler 18.0 and SPSS 26.0.The core drugs and disease targets were searched,and gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis were performed on the targets of their therapeutic action for palpitation.Results A total of 220 prescriptions were collected,involving 192 flavors of traditional Chinese medicines,with a cumulative medication frequency of 3978 times,and 18 flavors of high-frequency medicines.The medicines were mainly tonics,sedative,and promoting blood circulation for removing blood stasis.The distribution of medicinal properties were mainly warm,cold and flat.The medicinal flavors were mainly sweet,bitter and pungent,and channel tropism were mostly heart,liver and spleen channel.Association rule analysis showed that Radix Angelicae Sinensis,Radix et Rhizoma Salviae Miltiorrhizae,Radix et Rhizoma Glycyrrhizae,Radix Ophiopogonis,and Radix Astragali were the core drugs.Cluster analysis showed that there was 3 cluster combinations.In the network pharmacology part,there were 181 targets intersected by drug combinations and diseases.KEGG analysis showed that the core drugs for palpitation mainly involved signaling pathways such as phosphoinositide 3-kinase/protein kinase B,hypoxia-inducible factor-1,mitogen-activated protein kinase,interleukin-17,etc.GO analysis obtained 1000 GO pathways,of which 760 were biological processes,93 were cellular components,and 147 were molecular functions.Conclusion In the treatment of palpitation,Li Yaping advocates benefiting qi and promoting yang,removing blood stasis and eliminating turbidity,and tranquilizing the mind,emphasizing the"two hearts in the same adjustment",and treating the heart and liver at the same time,taking into account the spleen and stomach,and the combination of core medicines can intervene in the course of palpitation through multi-components,multi-targets,and multi-pathways,which is of great significance for the treatment of palpitation in the clinical setting.

ObjectiveTo evaluate the efficacy and safety of topical Bisaitong （鼻塞通） in treating moderate-to-severe allergic rhinitis （AR）. MethodsA randomized， positive-controlled， non-inferiority clinical trial design was adopted. Totally， 108 cases of moderate-to-severe AR were randomly divided into Bisaitong group and mometasone furoate group，with 54 cases in each group. The Bisaitong group was treated with Bisaitong smeared at the nasal cavity twice a day， and the mometasone furoate group received inhalation of mometasone furoate nasal spray 100 μg in each nostril， once a day. Both groups were treated for 4 weeks and followed up after additional 4 weeks. Both groups were compared on the rhinoconjunctivitis quality of life questionnaire （RQLQ）， rhinoconjunctivitis total symptom score （RTSS）， visual analogue score （VAS） of sneezing， runny nose， nasal itching， nasal congestion degree， days of AR episodes at enrollment， after 2- and 4-week， and at follow-up. The peripheral blood eosinophil （EOS） count and percentage （EOS%）， serum eosinophil cationic protein （ECP）， serum dust mite， dermatophagoides farinae， and cockroach allergen-specific IgE （sIgE） levels were compared between groups at enrollment and after 4-week treatment. Drug overuse rate was calculated， and the safety was evaluated. The analysis of all efficacy outcomes was based on both full analysis set （FAS） and per-protocol set （PPS）. ResultsThe lower limit of the 95% confidence interval for the differences in RQLQ scores were greater than -0.6 measured after 2- and 4-week treatment and at follow-up compared to that measured at the enrollment in both groups， indicating of the Bisaitong group being non-inferior to the mometasone furoate group. There was no statistically significant difference between groups on RTSS score， VAS scores of sneezing， runny nose， nasal itching， nasal congestion degree and days of episodes at all timepoints （P＞0.05）， but each outcome changed significantly over time in both groups （P＜0.01）. The differences between groups in EOS count， EOS%， ECP levels， serum dust mite， dermatophagoides farinae， cockroach sIgE levels， and drug overuse rate were not statistically significant at enrollment and after 4-week treatment （P＞0.05）. Adverse events occurred in eight cases （15.10%） in the Bisaitong group and five cases （9.30%） in the mometasone furoate group， showing no significant difference between groups （P＞0.05）. ConclusionTopical Bisaitong is non-inferior to mometasone furoate nasal spray in the treatment of moderate to severe AR in terms of clinical symptom relief，reduction in the episodes， improvement of quality of life， and sound safety.

Danggui Liuhuangtang is the 47^th of the 100 famous classical formulas published by the National Administration of Traditional Chinese Medicine， and is known as the holy medicine for night sweat. By bibliometrics， the authors collected the ancient books on Danggui Liuhuangtang and screened out 269 valid data， involving 156 ancient books of traditional Chinese medicine. The analysis on the historical origin， disease syndromes， pathogenesis， composition， dosage， preparation， usage， and processing of Danggui Liuhuangtang found that this famous classical formula originated from Secret Book of the Orchid Chamber （《兰室秘藏》） written by LI Dongyuan， and is composed of Angelicae Sinensis Radix， Rehmanniae Radix， Rehmanniae Radix Praeparata， Phellodendri Chinensis Cortex， Scutellariae Radix， Coptidis Rhizoma and Astragali Radix. It has the functions of nourishing Yin， reducing fire， consolidating exterior and stopping sweating， and mainly treats night sweat due to Yin deficiency and fire exuberance. In the later generations， disease syndromes are mostly treated based on LI Dongyuan's theory， and have expanded to more than 30 kinds （339 in total）， among which night sweat （208） was the most， accounting for 61.36% of the total disease syndromes， followed by spontaneous sweating （38）， accounting for 11.21%. Additionally， it was found that Danggui Liuhuangtang was widely used in modern clinical practice for various disease syndromes. Among them， endocrine disease （77， 28.21%） was predominant， followed by gynecological disease （48， 17.58%）， and pediatric disease （24， 8.79%）. Although Danggui Liuhuangtang treats many disease syndromes， their pathogenesis was always yin deficiency and fire exuberance. Through the systematic excavation of the ancient books on Danggui Liuhuangtang and the analysis of its modern clinical application， this paper probed into the historical evolution and confirmed the key information of the formula， providing detailed literature basis for the research and development application of famous classical formulas.

Dopamine is the precursor of a variety of natural antioxidant compounds. In the body, dopamine acts as a neurotransmitter that regulates a variety of physiological functions of the central nervous system. Thus, dopamine is used for the clinical treatment of various types of shock. Dopamine could be produced by engineered microbes, but with low efficiency. In this study, DOPA decarboxylase gene from Sus scrofa (Ssddc) was cloned into plasmids with different copy numbers, and transformed into a previously developed L-DOPA producing strain Escherichia coli T004. The resulted strain was capable of producing dopamine from glucose directly. To further improve the production of dopamine, a sequence-based homology alignment mining (SHAM) strategy was applied to screen more efficient DOPA decarboxylases, and five DOPA decarboxylase genes were selected from 100 candidates. In shake-flask fermentation, the DOPA decarboxylase gene from Homo sapiens (Hsddc) showed the highest dopamine production (3.33 g/L), while the DOPA decarboxylase gene from Drosophila Melanogaster (Dmddc) showed the least residual L-DOPA concentration (0.02 g/L). In 5 L fed-batch fermentations, production of dopamine by the two engineered strains reached 13.3 g/L and 16.2 g/L, respectively. The residual concentrations of L-DOPA were 0.45 g/L and 0.23 g/L, respectively. Finally, the Ssddc and Dmddc genes were integrated into the genome of E. coli T004 to obtain genetically stable dopamine-producing strains. In 5 L fed-batch fermentation, 17.7 g/L of dopamine was produced, which records the highest titer reported to date.

Objective To summarize the clinical characteristics of SLE patients complicated with Listeria monocytogenes meningitis (LMM).Methods The clinical manifestations,systemic involvements,laboratory tests,cerebrospinal fluid (CSF) examinations,treatment and prognosis of SLE inpatients combined with LMM in Peking Union Medical College Hospital during Janurary 2000 to December 2015 were retrospectively analyzed.Results Eight SLE patients with LMM accounted for 0.14％ of the 5 675 hospitalized SLE patients.Seven were female and 1 was male,with the mean age of (35±16) year.Headache (7/8) was the most common neurological symptom followed by positive meningeal irritation sign (5/8),unconsciousness (3/8) and nausea or vomiting (2/8).Increased intracranial pressure was found in 7 cases and 4 of them were even higher than 330 mmH2O.CSF protein elevated in 6 cases and CSF glucose decreased in 6 cases.LMM often occurred in inactive or mild active SLE with the average SLE disease activity index (SLEDAI) score of 4.7±1.5.Systemic manifestations included hematologic changes (6/8),rashes (4/8),renal involvement (4/8) and arthritis (3/8),etc.Treated by autibiotics such as penicillin and medications for SLE,7 patients achieved clinical improvements,1 patient died.Conclusion LMM is one of the opportunistic infections in SLE patients and tends to occur in inactive lupus cases.There are unspecific clinical and laboratory features and CSF changes which maybe overlap and mix up with systemic manifestations of SLE.That's why it is necessary to take continuous cultures of CSF.Early identification and appropriate treatment lead to prognostic improvement of these patients.

OBJECTIVE:To study the feasibility of overflow dissolution method for evaluating the drug in vitro sustained re-lease performance. METHODS:Overflow dissolution method was established by simulating the drugs elimination in vivo. Using Nifedipine sustained-elease tablets(Ⅰ)from 2 different manufacturers as model drug A,B,concentration-time curve,cumulative release rate- time curve,release velocity-time curve of model drugs in release pool at 3 different overflow speed (0,1.50,3.00 mL/min)were investigated. RESULTS:When overflow speed was 0,the cumulative dissolution was consistent with that of the con-ventional dissolution method. As the overflow speed increased,cmax of drug A,B was decreased [A:(8.89±0.20),(5.21±0.04), (3.51±0.03)μg/mL;B:(7.62±0.05),(4.80±0.09),(2.89±0.04)μg/mL];cumulative release rate was increased [A:(85.47± 2.45)%,(94.29 ± 2.44)%,(96.04 ± 2.56)%;B:(73.28 ± 1.13)%,(78.46 ± 1.94)%,(82.50 ± 1.69)%] ;tmax was ahead (A:1.5,1.0,0.5 h;B:2.0,1.0,0.5 h). CONCLUSIONS:Overflow dissolution method has avoided the inhibition of too large drug concentration on drug release,making complete drug release and more accurate evaluation of in vivo sustained release performance of the preparation.
