Objective: To investigate the factors affecting the development of malnutrition among the elderly patients with type 2 diabetes mellitus (T2DM), so as to provide insights into the prevention of malnutrition among the elderly patients with T2DM. Methods: Elderly T2DM patients at ages of 60 years and older admitted to Hangzhou First People's Hospital affiliated to Zhejiang University School of Medicine from June 2022 to June 2023 were recruited. Patients' demographics, number of medicines administered and comorbidities were collected using questionnaire surveys, and glycosylated hemoglobin (HbA1c), serum albumin (ALB) and hemoglobin levels were collected from medical records. The nutrition status was assessed with the new version of the Mini Nutritional Assessment Short Form (MNA-SF). Factors affecting the development of malnutrition were among the elderly T2DM patients identified using a multivariable logistic regression model. Results: A total of 382 elderly T2DM patients were enrolled, including 226 men (59.16%) and 156 women (40.84%) and with a mean age of (70.06±8.41) years. The prevalence of malnutrition was 22.25% among participants. Multivariable logistic regression analysis identified age (70 to 79 years, OR=1.261, 95%CI: 1.007-1.158; 80 years and older, OR=3.285, 95%CI: 1.618-6.662), three and more types of comorbidities (OR=2.790, 95%CI: 1.254-5.191), use of multiple medicines (OR=3.501, 95%CI: 1.841-6.658), sleep disorders (OR=1.613, 95%CI: 1.120-2.322), regular exercises (OR=0.280, 95%CI: 0.115-0.614), serum ALB of 35 g/L and greater (OR=0.272, 95%CI: 0.102-0.560) and HbA1c of 7% and higher (OR=2.914, 95%CI: 1.445-5.881) as factors affecting the development of malnutrition among elderly patients with T2DM. Conclusions The risk of malnutrition is associated with age, types of comorbidities, use of multiple medicines, sleep disorders, regular exercise, HbA1c and ALB among the elderly patients with T2DM. Periodical nutrition screening and intensified health education are recommended for T2DM patients.

AIM:To observe the anti-scarring effects and safety of triamcinolone acetonide(TA)-loaded hydrogel sustained-release sheeting on stab incision glaucoma surgery(SIGS)with “one-step tunnel method” in rabbit eyes.METHODS:A total of 48 healthy New Zealand white rabbits were randomly selected and divided into 4 groups(12 rabbits in each group), trabeculectomy(Trab)group, SIGS group, polyvinyl alcohol hydrogel(PVAH)sheeting was implanted under the conjunctiva flap during SIGS(PVAH group), and hydrogel sustained-release sheeting loaded with TA was implanted under the conjunctiva flap during SIGS(TA/PVAH group). On the 1, 2, 3, and 4 wk after surgery, the intraocular pressure, filtering bubble morphology, anterior chamber reaction, and other complications were observed and recorded in each group. Then animals were euthanized, and the surgery area tissues of right eye were taken for pathological tissue paraffin section. Masson staining, picric acid-Sirius rose red staining, as well as α-smooth muscle actin(α-SMA)and fibroblast growth factor 2(FGF2)immunohistochemistry staining was performed on every section. The infiltration of inflammatory cells, proliferation of fibroblasts and synthesis of type I and type III collagen fibers in local tissues were observed. The average positive area ratio of α-SMA and FGF2 antibody immunohistochemical staining in each group was calculated and compared.RESULTS: The TA/PVAH group maintained diffuse and elevated functional filtering blebs, while flat filtering blebs appeared in Trab, SIGS and PVAH groups at 2 wk after surgery. Functional filtering blebs were present in 1 eye(33%), 2 eyes(67%)in the PVAH and TA/PVAH group at 4 wk after surgery, respectively, while the other filtering blebs were flattened. Masson staining showed that the hydrogels in PVAH and TA/PVAH groups did not degrade at 4 wk after surgery. Compared with the Trab and SIGS groups, the filtration passages were more obvious, with less collagen fiber proliferation. Sirius red staining showed that the expression of type I collagen and type III collagen in the TA/PVAH group was less than that in the Trab group, SIGS group and PVAH group at 4 wk after surgery. Immunohistochemical staining showed that the α-SMA expression in the TA/PVAH group was significantly lower than that in the Trab and SIGS groups at 1 wk after surgery(P<0.01). The α-SMA expression was the highest in the Trab and SIGS groups at 2 wk after surgery, while the α-SMA expression in the PHAP and TA/PVAH groups was significantly lower than that in the first two groups(P<0.01). Compared with the Trab group, the expression of FGF2 in the PVAH and TA/PVAH group was significantly increased at 1, 2, 3 and 4 wk after surgery(P<0.05). Compared with the SIGS group, FGF2 expression in the TA/PVAH group was significantly increased at 4 wk after surgery(P<0.05).CONCLUSION:In SIGS surgery of rabbit eyes, implanting hydrogel sustained-release sheeting loaded with TA under conjunctival flap can effectively inhibit the scarring of the filtering bleb, which may be the interaction of the anti-scar effect of TA and the stent function of hydrogel.

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 clinical effect of flexible using Guizhi Fuling pill and Siwei Jianbu decoction in treating the diabetic nephropathy patients,and to observe its effect on inflammatory indicators and hypercoagulabale state.Methods A total of 78 patients diagnosed with syndrome of intermin-gled water and blood stasis diabetic nephropathy in Wenzhou TCM Hospital of Zhejiang Chinese Medical University from January to December 2022 were selected and divided into observation group and control group by random number table method,with 39 cases in each group.The control group was treated with conventional western comprehensive therapy,while the observation group was treated with Guizhi Fuling pill and Siwei Jianbu decoction on the basis of control group.Both groups were treated for 8 weeks.The TCM syndrome score,24h urinary protein quantity,serum creatinine(SCr),blood urea nitrogen(BUN),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),fibrinogen,D-dimer,alanine aminotransferase(ALT),aspartate aminotransferase(AST)were compared between two groups before and after treatment.Results After treatment,the TCM syndrome score,24h urinary protein quantity,SCr,BUN,IL-6,TNF-α,fibrinogen and D-dimer in two groups were significantly lower than before treatment(P<0.05).The TCM syndrome score,24h urinary protein quantity,SCr,IL-6,TNF-α,fibrinogen and D-dimer in observation group were significantly lower than those in control group(P<0.05).The total effective rate of observation group was significantly higher than that of control group(χ2=6.241,P=0.044).There was no adverse reaction between two groups after treatment,and there was no significant difference in liver function indexes before and after treatment(P>0.05).Conclusion Flexible using Guizhi Fuling pill and Siwei Jianbu decoction has a good therapeutic effect on syndrome of intermin-gled water and blood stasis diabetic nephropathy,which can reduce clinical symptoms of patients,reduce 24h urinary protein quantity and improve renal function,which is speculated to be related to reducing inflammation and improving hypercoagulabale state.

ObjectiveTo observe the effect of Kinesio taping on salivation after stroke. MethodsFrom October, 2019 to January, 2021, 40 patients with salivation after stroke were randomly divided into control group (n = 20) and experimental group (n = 20). Both groups received routine medicine, routine rehabilitation for dysphagia and rehabilitation nursing, while the experimental group received Kinesio taping in addition, for three weeks. They were assessed with Functional Oral Intake Scale (FOIS), Water Swallow Test (WST) and Teacher Drooling Scale (TDS) before and after treatment. ResultsOne case dropped in the experimental group. The scores of FOIS, TDS and WST improved in both groups after treatment (|Z| > 2.000, P < 0.05), and improved more in the experimental group than in the control group (|Z| > 3.045, P < 0.01). ConclusionKinesio taping may relieve the salivation of patients with dysphagia after stroke.

Objective:To explore the establishment and effect of short-term training path for prenatal ultrasound diagnosticians in primary hospitals.Methods:A total of 105 trainees from in total 5 batches of the "prenatal ultrasound screening training base" in Chongqing were selected as the research objects, and a combination of multiple teaching methods was used to carry out specialized training for primary prenatal ultrasound screening doctors before and after training. Theoretical examinations and practical operation assessments were performed, and after training, remote image quality control and continuous improvement methods were established for trainees to assess training effectiveness. SPSS 21.0 was used for t test, Wilcoxon test and chi-square test. Results:After training, the results of the theoretical examinations and practical operation examinations of the trainees were higher than those before the training ( P<0.05), and after the completion of the training, the number of trainees who returned to their original units to carry out prenatal ultrasound examination, the average number of prenatal ultrasound examinations per month and the number of referrals to higher prenatal diagnosis centers of each trainee increased significantly ( P<0.05).

Objective:To analyze the phenotype and genotype of two Chinese family with inherited dysfibrinogenemia and the molecular pathogenic mechanism.Methods:In the probands and their family members, coagulation routine, fibrinogen activity(Fg∶A) and fibrinogen antigen(Fg∶Ag) were detected . To find the mutation and exclude single nucleotide polymorphisms, all the exons and exons-intron boundaries of fibrinogen genes ( FGA, FGB and FGG) were amplified by Ploymerase Chain Reaction (PCR), then sequenced. Bioinformatics prediction softwares were used to predict and score the change of function caused by the variant. PyMol were used to analyze the structure of protein caused by the variant. Clustal X software was used to analyze the conservation of the mutant amino acids. Results:The thrombin time(TT) of the two was slightly prolonged and could not be corrected by protamine sulfate, and the fibrinogen activity was significantly reduced (1.25 g/L and 1.17 g/L), but the fibrinogen antigen content was normal, respectively (3.50 g /L and 3.81 g/L). Genetic analysis showed that both probands were heterozygous missense variants( FGB exon 7 c. 1115 T>A (p.Val372Glu)), both of which originated from the paternal line. The prediction results of the four bioinformatics softwares indicate that this variant could be disease causing. Clustal X software showed that Val372 is highly conserved among homologous species. Based on the guidelines of the American College of Medical Genetics and Genomics, c. 1115 T>A was predicted to be likely pathgenic(PM2+ PP1+ PP2+ PP3+ PP4). PyMol shouwed p. Val372Glu variant changes the secondary structure and three-dimensional structure of fibrinogen protein were changed caused by p. Val372Glu variant. Conclusion:Inherited dysfibrinogenemia of the probands maybe caused by variant of FGB c. 1115 T>A(p.Val372Glu), and the variant was firstly reported.

Objective: To analyze the feasibility of prenatal ultrasound quantitative measurement of the angles between trachea and bilateral bronchi as a new diagnostic tool for fetuses with heterotaxy syndrome. Methods: The angles between trachea and bilateral bronchi were measured at 18-34⁺⁶ gestational weeks for 200 fetuses with normal ultrasound findings (normal group) and 41 fetuses with heterotaxy syndrome [35 right atrial isomerisms (right group) and six left atrial isomerisms (left group)] diagnosed by ultrasound and confirmed after abortion or induction (case group) in Chongqing Health Center for Women and Children from October 2015 to December 2018. Scatter plots of left/right bronchus angle (α/β) ratios were drawn. Differences in bilateral bronchus angles between the three groups were statistically analyzed using one-way analysis of variance and paired t-test. Results: In the normal group, scatter plots showed the α/β ratios were relatively constant at 0.8-1.0 with larger β than α (t=-33.14, P<0.05), indicating that the right bronchus always went more steeply than the left one. In the case group, the α/β ratios were around 1.0. In the right group, the α value increased and was close to the β value [(153.90±5.43)° vs (156.02±5.59)°, t=-2.56, P>0.05] and presented as bilateral right bronchial angle; in the left group, the β value decreased and was close to the α value [(147.38±3.16)° vs (148.82±5.56)°, t=-1.18, P>0.05] and presented as bilateral left bronchial angle. There were significant differences in the α and β values among the normal group, the right and left groups (all P<0.05), and the bronchial angles of the right group were both greater than those of the left group (all P<0.05). Conclusions Prenatal ultrasound measurement of the angles between trachea and bilateral bronchi can be used as an indirect indicator for the diagnosis of heterotaxy syndrome.

OBJECTIVE: To explore molecular etiology and clinical characteristics of two pedigrees affected with hereditary factor VII(FVII) deficiency. METHODS: The nine exons and flanking sequences of the F7 gene of the probands were amplified by PCR. The amplicons were analyzed by direct sequencing. Suspected mutations were subjected to SWISS-MODEL modeling and analysis of protein structure change by Pymol software and conservation of amino acids across various species. RESULTS: For proband of pedigree 1, the prothrombin time (PT), FVII activity (FVII:C) and FVII antigen (FVII:Ag) were 36.3 s, 3%, 53.56%, respectively. Sequencing revealed a compound heterozygous variants of c.80_81delCT and c.1371G>T(p.Arg439Ser). His son carried a heterozygous c.1371G>T (p.Arg439Ser) variant. For proband of pedigree 2, the PT, FVII:C and FVII:Ag were 22.3 s, 4%, 1.58%, respectively. Sequencing has revealed a compound heterozygous c.278G>T(p.Arg75Met) missense variant in exon 3 and c.1278T>G (p.His408Gln) in exon 9 of the F7 gene. His mother and son both carried a heterozygous c.278G>T(p.Arg75Met) variant. Three-dimensional simulation and homology analysis revealed that the p.Arg439Ser and p.Arg75Met can respectively alter part of hydrogen bonds and two highly conserved amino acids. CONCLUSION Two novel heterozygous missense variants of the F7 gene [c.1371G>T(p.Arg439Ser) and c.278G>T(p.Arg75Met)] probably account for the decrease of factor VII in the two pedigrees.

Objective? To investigate and understand the duty fulfillment of professional role among community nurses in Sichuan Province. Methods? From August 2016 to December 2016, we selected 969 community nurses at 56 communities in Sichuan by convenience sampling combined with cluster sampling. The duty fulfillment of professional role of community nurses was investigated with the role behavior frequency questionnaire for community nurses. Epidata 3.1 was used to data entry and SPSS 19.0 was used to statistical analysis on the data. Results? Among community nurses, the highest scores of fulfillment frequency of role behavior were organizers and managers (2.63±0.91), and the lowest scores were service object spokesmen (2.11±0.87). There were statistical differences in the scores of different role behavior frequencies (P＜0.01). At the same time, there were statistical differences in the duty fulfillment of professional role among community nurses with different areas and professional levels (P＜0.05). Conclusions? The role function of service object spokesmen of community nurses needs to be strengthened. Community managers of different areas should set the type of post and formulate service contents according to regional characteristics and professional levels of community nurses.
