Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective To investigate the effects and mechanism of Zhachong Shisanwei Pills on rats with cerebral ischemia.Methods Totally 75 rats were randomly divided into sham-operation group,model group,positive drug group(Ginaton,21.6 mg/kg),and Zhachong Shisanwei Pills low-,medium-,and high-dosage groups(81,162,324 mg/kg).Each treatment group was given the corresponding drug by gavage for 5 days.On the 6th day,a cerebral ischemia rat model was prepared by suture method.After 24 hours of modeling,the drugs were given in the same manner for 2 days.Neurological function scoring,horizontal beam walking scoring,and grip strength testing were performed on rats.TTC staining was used to detect the cerebral infarction rate,HE staining and Nissl staining were used to observe the morphology of brain tissue.TUNEL staining was used to detect the apoptosis rate of brain tissue cells.Differential genes in the treatment of cerebral ischemia using Zhachong Shisanwei Pills were screened by transcriptomics,and RT-qPCR,immunohistochemistry and Western blot were used to detect differential gene mRNA and protein expression.Results Compared with the sham-operation group,the model group rats showed a decrease in neurological function scores,horizontal beam walking scores,grip strength,an increase in cerebral infarction rate,neuronal nucleus condensation,vacuolar changes,widened intercellular spaces,the number of Nissl bodies reduced,and the apoptosis rate increased(P<0.01,P<0.001);compared with the model group,the Zhachong Shisanwei Pills medium-dosage group showed an increase in neurological function score,horizontal beam walking score,and grip strength in rats,a decrease in cerebral infarction rate,a lower degree of neuronal damage,an increase in the number of Nissl bodies,and a decrease in cell apoptosis rate(P<0.05,P<0.01).Transcriptome and bioinformatics analysis screened the Hippo signaling pathway related to the anti-cerebral ischemia effect of Zhachong Shisanwei Pills.The key genes of this pathway,mammalian sterile line 20 like kinase(MST1)1,Yes related protein(YAP)1,large tumor suppressor kinase(LATS)1,and TEA domain family member(TEAD)1 were detected.The results showed that the expression of MST1 mRNA and protein in brain tissue of model rats significantly increased,while the expressions of YAP1,LATS1,TEAD1 mRNA and protein significantly decreased;Zhachong Shisanwei Pills could down-regulate the expression of MST1 in brain tissue of model rats,and up-regulate the expressions of YAP1,LATS1 and TEAD1.Conclusion Zhachong Shisanwei Pills may exert anti-cerebral ischemia effects through the Hippo signaling pathway.

【Objective】 To explore the effectiveness of creating the obstructive sleep apnea hypopnea syndrome (OSAHS) animal model of glossocoma using the botulinum toxin type A in white rabbits, and to explore the effectiveness and safety of magnetic traction hyoid suspension operation in the OSAHS animal model of glossocoma. 【Methods】 A total of 12 adult male experimental white rabbits were randomly divided into two groups. The animals in the experimental group were injected with 0.4 mL (10 U) of botulinum toxin type A in the genioglossus muscle to construct the OSAHS animal model of glossocoma. The animals in the control group were injected with 0.4 mL of normal saline. We designed and 3D printed a polyacrylate shell that could be loaded with inner and outer neodymium iron boron (NdFeB) magnets. After the modeling, a polyacrylate shell with the inner magnet device was fixed on the hyoid bone of the animals in the experimental group. All animals in the experimental group wore the polyacrylate orthotic neck brace containing the outer magnet 10 days after the operation. The arterial blood oxygen detector was used to record the oxygen saturation (SaO2) of the femoral artery, and multi-slice CT plain scan was used to measure the diameter of the narrowest part of the upper airway. 【Results】 The animals in the experimental group gradually showed decreased activity, labored breathing, blue lips and ear margins and other manifestations of hypoxemia 5 days after intramuscular injection of botulinum toxin type A in the genioglossus, and their body weight dropped from (3.72±0.21)kg to (3.40±0.20)kg, the average SaO2 of the femoral artery decreased from (93.84±5.14)% to (84.00±3.35)%, and the diameter of the narrowest part of the upper airway decreased from (4.83±0.47)mm to (3.52±0.83)mm (P<0.05). In the control group, the animals’ weight, the average SaO2 of the femoral artery, and the diameter of the narrowest part of the upper airway did not significantly change before and after injection of normal saline into the genioglossus muscle (P>0.05). The animals in the experimental group completed the magnetic traction hyoid suspension surgery. After wearing the orthotic neck brace containing an external magnet for hyoid magnetic traction, the food intake and activity of the animals in the experimental group increased, the color of the lips changed from purple to pink, the SaO2 of the femoral artery increased significantly to (90.44±5.95)%, and the diameter of the narrowest part of the upper airway increased significantly to (4.42±0.15)mm (P<0.05). 【Conclusion】 The genioglossus muscle injection of botulinum toxin type A in white rabbits could successfully establish the OSAHS animal model of glossocoma. Magnetic traction hyoid suspension surgery in the treatment of OSAHS animal model could effectively correct the upper airway stenosis related symptoms and hypoxemia caused by glossocoma.

Objective:To observe the rehabilitation effect of Baduanjin combined with elastic band training on elderly patients with sarcopenia. Methods:From January 2019 to January 2021, 120 elderly sarcopenia patients in our hospital who met the inclusion criteria were divided into two groups according to the random number table method, with 60 in each group. The control group was given conventional treatment intervention for sarcopenia, and the observation group was Baduanjin exercises combined with elastic band training on the basis of the control group. Both groups were intervened for 12 weeks. The skeletal muscle index (SMI), muscle grip strength, short physical performance battery (SPPB) and Modified Barthel Index (MBI) were used to compare between two groups before and after the intervention. Results:After treatment, the SMI index [(6.77 ± 1.03) kg/m 2vs. (6.35 ± 1.12) kg/m 2, t=2.14], muscle grip strength [(23.06 ± 3.48) kg vs. (19.41 ± 3.79) kg, t=5.50], SPPB score [(9.12 ± 2.24) vs. (7.85 ± 2.13), t=3.18] and MBI score [(82.43 ± 20.75) vs. (64.36 ± 19.42), t=4.93] of the observation group were significantly higher than those in the control group ( P<0.05). After treatment, the distribution of muscle activity function in the observation group was significantly better than that of the control group ( Z=-2.28, P=0.023).

Objective:To explore the diagnosis, surgical methods and therapeutic effect of primary duodenal malignant tumor.Methods:The clinical data of 116 patients with primary duodenal malignant tumor from January 2010 to December 2018 were retrospectively analyzed.Results:Among 116 patients, adenocarcinoma was in 74 cases, interstitial tumor was in 25 cases, carcinoid was in 9 cases, the others was in 8 cases. Before operation, duodenoscopy was performed in 107 cases, and CT examination was performed in 76 cases. There were 57 cases of pancreaticoduodenectomy, 15 cases of duodenal segmental resection, 13 cases of subtotal gastrectomy and duodenal bulbar resection, 13 cases of duodenal partial resection, and 18 cases of palliative short circuit operation. The total incidence of postoperative complication was 31.9% (37/116), including pancreatic fistula in 8 cases (grade B 5 cases, grade C 3 cases), biliary fistula in 6 cases, abdominal infection in 5 cases, pulmonary infection in 4 cases, intestinal fistula in 3 cases, delayed gastric emptying in 3 cases, and hemorrhage in 8 cases. Four cases (3.4%) died during the perioperative period. Single factor Cox regression analysis result showed that the postoperative survival time was related to the tumor differentiation degree, operation method, tumor infiltration degree and lymphatic metastasis ( P<0.05 or <0.01); multi-factor Cox regression analysis results showed that the operation method, tumor infiltration degree and lymphatic metastasis were the independent risk factors for the postoperative survival time of patients with primary duodenal malignant tumor ( P<0.05). The patients were followed up until June 2021, and 9 cases were lost to follow-up. Kaplan-Meier survival curve analysis result showed that the postoperative overall 1-,3- and 5-year survival rates were 82.11%, 57.56% and 33.11%, respectively. Conclusions:Adenocarcinoma is the main primary malignant tumor of duodenum. Duodenoscopy and CT are the main examination methods. Radical resection is the most effective treatment for primary duodenal malignant tumor, and pancreaticoduodenectomy is the first choice. Surgical method, tumor infiltration degree and lymphatic metastasis are the independent risk factors affecting the prognosis of patients.
