Objective To investigate The effect of Heat shock protein 70(HSP70) antisense oligonucleotides (ASO)to bladder carcinoma in mouse loaded with tumor.Methods The 40 mice loaded with tumor subcutaneously were established by cultured BIU-87 cells,and divided into 4 groups randomly when the subcutaneous neoplasms grew to about 100 mm3,namely,HSP70 mRNA ASO plus mitomycin C(MMC)group;HSP70 mRNA ASO group;MMC and blank control.HSP70 mRNA ASO were injected into neoplasms,10mmg/kg weight,twice every week,and MMC 0.1mg/kg weight,twice every week,and the above schemes were replaced with normal saline to blank.The neoplasms were peeled off,photograghed and weighed in 30 days.HSP70 expressions were examined with reverse transcription polymerase chain reaction (RT-PCR),mierovaseular density(MVD)was evaluated by immunohis to chemical staining and the tumor cells apoptosis was detected by terrainal deoxynucleotidyl transferase(TdT)-mediated dUTP-biotin nick end labeling technique (TUNEL).Results The tumor inhibition rate in ASO+MMC surpassed 50%.more than ASO or MMC respectively,and the differences were significantly(P＜0.05).The ASO and MMC exceeded blank group respectively(P＜0.05).The ASO was the same as the MMC(P＞0.05).The apoptotic index(AI)in ASO+MMC surpassed the other three groups (P＜0.05).The difference between ASO and MMC was not significant (P＞0.05),while the A1 of ASO or MMC was more than blank respectively(P＜0.05).The results of MVD were in accordance with the above results.Conclusion The injection of HSP70 mRNA ASO in tumor locally can inhibit neoplasm growth,and this effect might correlate with the inhibition of apoptosis and microvascular forming resulting from the ASO.

In this paper, duloxetine was chosen as the lead compound. The pharmacophores with 5-HT(1A) antagonism activity were used to replace the naphthyl of duloxetine. A series of duloxetine derivatives had been designed and synthesized and whose structures were confirmed with elemental analysis, MS and H NMR. All synthesized compounds were tested by tail suspension test and forced swimming test in vivo. The test results revealed that most of the compounds have shown better activity than duloxetine at the same dosage. Some of them are worth to be studied further.

An on-line solid phase extraction ( SPE ) coupled with HPLC-MS/MS method was developed to determine S-ammuxetine and R-ammuxetine in rat plasma. The sample preparation consisted of the following steps:A protein precipitation extraction used methanol and acetonitrile ( 50:50 , V/V ); an on-line SPE treatment to remove most matrixes in plasma;an enrichment and separation step used a C18 analytical column. S-and R-ammuxetine were determined by tandem mass spectrometry. The SPE column was a Retain PEP Javelin (10 mm × 2. 1 mm × 5 μm), while the chromatographic separation was achieved using a ZORBAX SB-C18 (50 mm × 2. 1 mm × 3. 5 μm) analytical column with an isocratic mobile phase composed of acetonitrile-water-formic acid (40:60:0. 1, V/V/V, 0. 3 mL/min). The selected reaction monitoring mode of the positive ion was performed and the precursor to the product ion transitions of m/z 292 . 1/154 . 0 and m/z 260. 4/116. 2 were used to measure S-ammuxetine, R-ammuxetine and internal standard (propranolol). The method was linear over a concentration range from 0 . 2 to 1000 μg/L with the correlation coefficients of 0 . 9903 and 0 . 9951 . The average intra-day precision values were 1 . 2% -12 . 0% for S-ammuxetine and 0. 4%-11. 2% for R-ammuxetine, respectively. The average recoveries were 94. 2%-101. 6% for S-ammuxetine and 94. 3% -109. 4% for R-ammuxetine. Compared to the literature, the sensitivity of this method increased dramatically. The present method has been successfully applied to the preclinical rat research of ammuxetine isomers following intragastric administration.

Objective:To compare the clinical efficacy of axillary transthoracic approach and posterior approach in the treatment of upper thoracic tuberculosis with vertebral clearance, bone graft fusion, and internal fixation surgery.Methods:Fifty five patients with upper thoracic tuberculosis admitted to Changsha Central Hospital, University of South China from March 2017 to March 2022 were selected and divided into axillary transthoracic group and posterior group according to different surgical approaches. The incision length, surgical time, intraoperative blood loss, and postoperative hospitalization time were compared between the two groups of patients. Two groups of patients were recorded for preoperative and postoperative pain visual analog scale (VAS) scores, Oswestry Disability Index (ODI) scores at 1 week, 3 months, and 12 months, preoperative and postoperative serum inflammatory indicators, CD4 + /CD8 + ratio of T lymphocyte subsets, and complications. Results:The incision length, operation time, and intraoperative blood loss in the axillary transthoracic group were significantly less than those in the posterior group, and the differences were statistically significant (all P<0.05). However, there was no statistically significant difference in postoperative hospitalization time between the two groups of patients ( P>0.05). The VAS and ODI scores of the two groups of patients showed significant improvement compared to preoperative levels at 1 week, 3 months, and 12 months after surgery (all P<0.05); And at 1 week and 3 months after surgery, the VAS scores of patients in the axillary transthoracic group were significantly lower than those in the posterior group (all P<0.05), and the ODI scores at 3 and 12 months after surgery were significantly lower than those in the posterior group (all P<0.05). The erythrocyte sedimentation rate and CRP levels of both groups of patients increased significantly one week after surgery compared with preoperative levels (all P<0.05), but the erythrocyte sedimentation rate and CRP levels basically returned to normal levels at three months after surgery. The CD4 + /CD8 + ratio of T lymphocyte subsets in both groups was lower than preoperative levels at one week after surgery, but with the continuation of treatment, the CD4 + /CD8 + ratio increased significantly at three months after surgery. Conclusions:Both axillary and posterior approaches can be used for surgical treatment of upper thoracic tuberculosis, but axillary and thoracic approaches have the advantages of less trauma, less bleeding, and faster recovery.

Non-human primates are the closest relatives of human beings and possess similar morphological， anatomical， physiological， and behavioral characteristics， making them indispensable in fields such as neuroscience， reproduction， infectious diseases， and drug research and development. Currently， the restrictions on using non-human primates in experiments are becoming increasingly stringent in Europe and the United States. These experiments have ethical particularities that are different from those involving ordinary animals， and they also pose ethical challenges such as lack of necessity assessment， no unified assessment standards， and ethical dumping hazards. Supervision and ethical review should be strengthened. The key points of their ethical review include the necessity of the experiments， the assessment of the harm-benefit ratio， and the implementation of the “3R” principles.

ObjectiveTo investigate the material basis of homologous and heterogeneous effect of Aurantii Fructus Immaturus（AFI） and Aurantii Fructus（AF） based on the total statistical moment analysis and molecular connectivity index（MCI）. MethodRelevant literature at home and abroad and Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform（TCMSP） were consulted to establish the chemical composition database of AFI and AF， and set up their fingerprints by ultra-high performance liquid chromatography（UPLC）， and the total statistical moments and similarity parameters of the fingerprint were calculated. According to MCI， all components of AFI and AF were divided into different component groups， the average values of 0-8^th order（⁰χ-⁸χ） MCI of the common component groups of AFI and AF were calculated. ResultThe values of total zero-order moment（AUC_T） of AFI and AF were （10.57±2.45）×10⁶， （5.09±0.89）×10⁶ μV·s， the values of total first-order moment（MCRT_T） were （11.57±1.58）， （12.10±1.29） min， the values of total second-order moments（VCRT_T） were（24.49±2.30）， （26.49±2.54） min²， respectively. It showed that qualitative and quantitative parameters of AFI and AF were significantly different. The components with high similarity such as neohesperidin， hesperidin and narirutin were screened as the common potential pharmacodynamic components of AFI and AF. The non-common components of AFI， such as alysifolinone and imperatorin， and the non-common components of AF， such as neoeriocitrin and isosakuranin， with high similarity were screened out as potential heterogeneous components of AFI and AF. The composition groups of AFI and AF were classified into six categories， and the similarities between the composition groups of AFI and AF and the total constituents were 0.872-0.979 and 0.918-0.997， the average values of ⁰χ-⁸χ MCI of alkaloids in AFI and AF were 3.65 and 3.14， the average values of ⁰χ-⁸χ MCI of flavonoids were 8.47 and 8.47， the average values of ⁰χ-⁸χ MCI of volatile oils were 2.71 and 3.48， respectively. It showed that there were some differences in MCI of chemical constituents（groups） between AFI and AF. ConclusionThe chemical constituents（groups） of AFI and AF not only differ in content and species， but also in structural characteristics and structure-activity relationship， which can provide a basis for further explaining the scientific connotation of homologous and heterogeneous effect of AFI and AF.

ObjectiveTo compare the similarities and differences of material basis for improving insulin resistance （IR） in different parts of Morus alba based on liquid-mass combination combined with network pharmacology and molecular docking technology. MethodUltra-high performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF-MS） was used to analyze the composition differences in different parts of M. alba. Sybyl-X2.1 was used to connect components with IR core targets， and the selection criterion was Total Score≥5. The "component-target-disease" network map was drawn. The total statistical moment standard similarity （TQSMSS） between the single target-component docking score data set and the total target-component docking score data set was calculated. The targets with higher TQSMSS were screened out， and the protein-protein interaction （PPI） network was constructed. The Gene Ontology （GO） functional analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis were performed using R language. ResultForty-one active components were obtained by UPLC-Q-TOF-MS. According to the total statistical moment （similarity） method， there were 20， 23， 30， and 27 targets with TQSMSS≥0.75 in Mori Ramulus， Mori Cortex， Mori Fructus， and Mori Folium， respectively. In the four M. alba medicinal sources， the functional order of the targets by GO enrichment analysis was Mori Fructus>Mori Folium>Mori Cortex>Mori Ramulus， which were involved in biological processes such as blood glucose homeostasis， glucose metabolism， and glucose transmembrane transport. The order of the four M. alba medicinal sources by KEGG pathway enrichment analysis was Mori Fructus>Mori Ramulus>Mori Folium>Mori Cortex， which were involved in the adenosine monophosphate-activated protein kinase （AMPK） energy metabolism signaling pathway， the insulin regulation-related signaling pathway， the anti-inflammatory and anti-oxidative stress signaling pathway， and so on. ConclusionThis research demonstrates that there are differences in the material basis for improving IR by different parts of M. alba， which provides references for the development of different parts of M. alba.
