Objective To investigate the safety and feasibility of peripheral vascular intervention via the ipsilateral transulnar access(TUA)due to failure of transradial access(TRA)puncture.Methods The clinical data of 2546 peripheral vascular interventions via TRA,which were performed at authors'hospital between January 2019 and December 2021,were retrospectively analyzed.Among the 2546 interventions,TRA puncture failed in 37 procedures,and in 27 of these patients the ipsilateral TUA puncture had to be adopted.The puncture success rate,surgical success rate and puncture approach-related complications of TUA of the 27 patients receiving ipsilateral TUA puncture were analyzed.Results The success rate of ipsilateral TUA puncture after TRA puncture failed was 96.3％(26/27),and in one patient transfemoral access(TFA)puncture had to be substituted because of the ulnar artery spasm.The total success rate of interventional procedures was 96.3％(26/27).No serious complications occurred,and the incidence of minor complications was 19.2％(5/26).Conclusion Preliminary results indicate that for the experienced TRA operators,using ipsilateral TUA puncture due to failure of TRA puncture is a safe and feasible strategy choice.

OBJECTIVE To identify Ginseng Flos and their confounds by using the high-throughput sequencing technology, and to verify the accuracy of high-throughput sequencing technology in species identification by using ITS2 sequencing technology. METHODS High-throughput sequencing was performed on the amplified products of Ginseng Flos adulterated samples, use cutadapt, PEAR, PRINSEQ, Usearch, RDP classifier, SINTAX software to obtain operational taxonomic unit(OUT) sequences, remove fungi, unclassified and other non-green plant sequences. To avoid false positives, delete OTU sequences with a sequence number <100 or base numbers <200 bp. The ITS2 amplification products of Ginseng Flos, Quinquefolii Flos, and Notoginseng Flos were sequenced. To verify the accuracy of high-throughput sequencing technology for species identification, MEGA 11.0 was used to construct neighbor joining system cluster tree, genetic distance, interspecific information loci and Blast analysis of ITS2 and OTU base sequences of Ginseng Flos, Quinquefolii Flos, and Notoginseng Flos. RESULTS A total of 54 653 valid sequences were obtained by high-throughput sequencing, the serial numbers of Ginseng Flos, Quinquefolii Flos, and Notoginseng Flos were OTU1, OTU2, OTU3, respectively, and the corresponding effective sequences were 31 325, 857 and 442, respectively. By performing a Blast search of ITS2 and OTU base sequences of each species, each species was supported. The genetic distance between Ginseng Flos and Quinquefolii Flos and Notoginseng Flos was 0.010 and 0.033, respectively. Ginseng Flos and Quinquefolii Flos, Notoginseng Flos had 2 and 7 information sites, respectively. The neighbor join system cluster tree showed that the species were clustered independently into one branch, with Ginseng Flos, and Quinquefolii Flos clustered as a large branch and juxtaposed with Notoginseng Flos. Ginseng Flos was the same as Quinquefolii Flos secondary structure, but with Notoginseng Flos there were three different positions but there were A, B and C differences between arm Ⅳ and arm Ⅰ of Notoginseng Flos. CONCLUSION The high-throughput sequencing technology can accurately identify Ginseng Flos, Quinquefolii Flos and Notoginseng Flos, and has a strong ability to identify adulterated samples, which provides a certain idea for the identification of commercial Ginseng Flos.

Objective:To analyze the incidence of liver function injury in patients infected with 2019-nCoV omicron variant and its influencing factors.Methods:The clinical data and laboratory findings of 897 COVID-19 patients infected with omicron variant in Zhejiang province from February 23 to July 14, 2022 were retrospectively analyzed. Patients were divide into liver function injury group ( n=243) and non-liver function injury group ( n=654) based on liver function indicators. The clinical characteristics and laboratory tests were compared between the two groups, and influencing factors of liver function injury were analyzed. SPSS 26.0 statistical software was used for data analysis. Results:The incidence of liver injury in this series was 27.09% (243/897). The median age of patients in liver injury group was older, the body mass index (BMI) was higher( Z=-6.237 and -2.166, both P<0.05), the proportions of patients with hypertension and diabetes, and with severe clinical classification were higher ( χ2=17.087, 27.509 and 12.945, all P<0.01) ; the proportion of vaccinated patients was lower ( χ2=17.766, P<0.01) than those in non-liver injury group. The levels of platelet, hemoglobin, albumin and potassium in liver injury group were lower than those in non-liver injury group ( Z=-4.631, -2.368, -10.593 and -2.141, all P<0.05), while serum ALT, AST, γ-GT, urea nitrogen, glucose and hs-CRP levels were higher than those in the non-liver injury group ( Z=-7.451, -8.663, -4.410, -3.824, -3.278 and -3.884, all P<0.01). Multivariate Logistic regression analysis showed that age ( OR=2.580, 95% CI 1.429-4.657, P=0.002), history of diabetes ( OR=3.650, 95% CI 1.698-7.849, P=0.001), and decreased hemoglobin ( OR=1.993, 95% CI 1.066-3.726, P=0.031) and increased hs-CRP ( OR=1.797, 95% CI 1.283-2.517, P=0.001) were risk factors associated with liver function injury, while vaccination ( OR=0.499, 95% CI 0.312-0.798, P=0.004) was the protective factor for liver function. Conclusion:Liver function injury is frequently observed in COVID-19 patients infected with omicron variant, which is linked to age, underlying disease, and elevated inflammatory markers; while vaccination can lower the risk of liver injury in infected patients.

OBJECTIVETo evaluate the effects of needling depth on clinical efficacy of lumbar disc herniation (LDH).

METHODSTen electronic databases, including China National Knowledge Infrastructure (CNKI), VIP Database, Chinese Biomedical Literature Database (CBM), Wanfang Database, MEDLINE, CENTRAL, CINAHL PLUS, AMED, Embase, PsycINFO, and 6 registry platforms of clinical trials were searched. All randomized controlled trials (RCTs) that compared the effect of needling depth on clinical efficacy of LDH were collected; in addition, the reference lists of the studies included were hand searched. Data were extracted independently by two reviewers. RevMan 5.3 was applied to carry out statistical analysis.

RESULTSTotally 8 716 articles were retrieved, and 10 RCTs were included after screening, involving 1 116 patients. The results showed the effects of deep acupuncture onrelievingpain, reducing the Oswestry disability index (ODI), improving total effective rate and Japanese Orthopaedic Association (JOA) were superior to those of shallow acupuncture in patients with LDH.

CONCLUSIONIt is preliminarily indicated that deep acupuncture is helpful to improve the therapeutic effect of LDH; however, due to the low research quality and small sample size, the evidence is insufficient, and more high-quality researches are needed to further confirm the results.

Performance management is a key strategy tool for a hospital to achieve its planned goals,and performance negotiation plays a key role in performance management which consists of performance planning,execution,evaluation and feedback.The negotiations emphasize differently in the negotiations,as short of which effective performance management is out of the question.To cultivate an incentive-oriented negotiation culture and build a negotiation system make a great difference in solving problems of performance management and promoting efficacy of hospital performance management.

A thermal desorption ( TD) device was developed and coupled to gas chromatography ( GC) or gas chromatography-mass spectrometry ( GC-MS ) for the qualitative and quantitative analysis of semi-volatile organic compounds on atmospheric particulate matters ( PM ) . The TD was operated by direct heating and placed on the GC injector, leading to high heating rate and easy transfer of analytes to GC without focusing of analytes by cold trap. For establishing the TD-GC method, the materials used for supporting PM samples, temperature and time of thermal desorption, and types of sample injection were investigated for detection of sixteen polycyclic aromatic hydrocarbons ( PAHs) and nine n-alkanes. The limits of detection of the proposed TD-GC method were in the range of 0. 014-0. 093 ng for PAHs, and 0. 016-0. 026 ng for n-alkanes, respectively, with the correlation coefficients of correlation above 0. 9975. The TD-GC method was applied to the determination of trace PAHs and n-alkanes on PM10 samples from three cities. The recoveries were in the range of 95%-135% ( PAHs) and 95%-115% ( n-alkanes) , respectively. Finally, the TD was coupled to GC-MS for comparison of the contents of PAHs and n-alkanes on PMx with different particulate size ( x=10 , 5, 2, 1, 0. 5, 0. 25, 0. 1).

OBJECTIVE: To investigate the clinical characteristics of ocular symptoms in patients with allergic rhinitis (AR) and the impact of the ocular symptoms on patients' quality of life. METHOD: AR patients' history and clinical data were collected and analyzed. One hundred cases were extracted from adult patients with and without ocular symptoms in each group and their quality of life were evaluated using rhino-conjunctivitis quality of life questionnaire (RQLQ). RESULT: Totally 1119 cases were collected and 859 cases had ocular symptoms. Of the patients with ocular symptoms, 582 cases were mild, 234 cases were moderate, 43 cases were severe. Eye itching was the most common symptom, followed by tears, hyperemia and swelling. Patients with ocular symptoms had longer disease history than non ocular symptom group (P < 0.05). There was a positive correlation between ocular and nasal symptoms (P < 0.01); patients with ocular symptoms had more severe nasal symptoms than patients without ocular problems; while patients with moderate to severe AR had more severe ocular symptoms than mild AR patients (P < 0.01). Female patients had higher incidence (P < 0.05) and ocular symptoms score (P < 0.05) than male. Children less than 10 years old had a relative lower incidence and score of ocular symptoms. While the incidence and score had an increasing trend for patients older than fifty. There was no difference regarding the type and number of allergen in the patients with and without ocular symptom. Moreover, patients with ocular symptoms had higher scores in the domains of non-nose/eye symptoms, practical problems, ocular symptoms, emotional function and total score in RQLQ than patients without ocular symptom. CONCLUSION It was common for the AR patients to have ocular symptoms, and ocular symptoms had obvious influence on the patients' quality of life. So controlling of the ocular symptoms should not be ignored during the diagnosis and treatment of AR.

OBJECTIVECellular senescence as one of the important steps against tumor is observed in many cancer patients receiving chemotherapy and is related to chemotherapeutic response. To investigate the effect of cisplatin on hepatocellular carcinoma, we treated HepG2 cells exhibiting wild-type TP53 with gradient concentrations of cisplatin.

METHODSThe inhibitory effects of cisplatin on human hepatoma HepG2 cells were detected by MTT assay and colony formation test. The changes in cell cycle were analyzed by flow cytometry, and cellular senescence was detected with senescence associated β-galactosidase (SA β-gal) staining. The relative mRNA expression levels of TP53, P21 and P19 was estimated using semi-quantitative real-time RT-PCR, and the protein expressions of P53 and P21 were detected using Western blotting.

RESULTSCisplatin induced irreversible proliferation inhibition and G1 phase arrest of HepG2 cells. Elevated levels of senescence-associated β-galactosidase was observed in HepG2 cells exposed to low doses of cisplatin. P19 expression immediately increased following cisplatin exposure and reached the maximum level at 48 h, followed then by a rapid decrease to the baseline level, whereas the expressions levels of TP53 and P21 mRNA increased continuously. Western blotting confirmed P53 and P21 expression changes similar to their mRNA expressions during cisplatin-induced cellular senescence in HepG2 cells.

CONCLUSIONOur results revealed a functional link between cisplatin and hepatocellular senescence. Cellular senescence induced by cisplatin as a stabile senescent cellular model can be used for further research.
