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.

Objective To investigate Iomoxicam,paracetamol,trarnadol in post-operative analgesia of surgical abortion.Methods 200 patients undergoing surgical abortion were randomly allocated into four groups:lornoxicam,paracetamol,tramadol and the control group.Intravenous anesthesia was conducted.Lomoxicam 16 mg,paracetamol 1000mg,tramadol 100 mg were administered before patients awaking.VAS scores and complications were observed post-operation.Pre-operative and post-operative salivary cortisol was detected.Results VAS scores were less in the 3 analgesic groups than in control group at 15,30 minutes post-operation(P＜0.05).VAS scores had no difference in all groups at 60,120 minutes.Cortisol was higher in the control on the next day(P＜0.05).Conclusion Post-operative analgesia was effective for surgical abortion.

Objective To explore the mediation role of university graduates' core self-evaluation played between perfectionism and job-selecting anxiety.Methods 200 university graduates were investigated by Chinese frost multidimensional perfectionism questionnaires,core self-evaluation scale and self-rating anxiety scale with convenience sampling method.Results ①Job-selecting anxiety had no distinct differences in gender,residence and the aspects of only-child(P＞0.05),but in different subjects,it was different(science and technology(1.79±0.49),culture and history(3.21±0.50),t=-4.38,P＜0.01).② University graduates' positive perfectionism was positively correlated with core self-evaluation (r=0.31,P＜ 0.01),while negatively correlated with job-selecting anxiety (r=-0.35,P＜0.01).University graduates' negative perfectionism was negatively correlated with core self-evaluation(r =-0.35,P＜ 0.01),while positively correlated with job-selecting anxiety (r =0.42,P＜ 0.01).Simultaneously core self-evaluation was negatively correlated with job-selecting anxiety (r=-0.46,P＜ 0.01).③ Core self-evaluation played a part of the intermediary role between negative perfectionism and job-selecting anxiety.The mediating effect was 30.0％ of the total effect.Core self-evaluation played a part of the intermediary role between positive perfectionism and job-selecting anxiety.The mediating effect was 34.5％ of the total effect.Conclusion Perfectionism as a personality trait can calculate the level of job-selecting anxiety.Core self-evaluation plays a part of the intermediary role between perfectionism and job-selecting anxiety.It is helpful to the working tactics of university graduates.

OBJECTIVETo analyze the imaging features of osteopoikilosis and its diagnosis knowledge.

METHODSThe imaging data of 9 patients with osteopoikilosis were analyzed retrospectively, including 6 familial cases and 3 sporadic cases. In 6 familial cases,there were 4 males and 2 females with an average age of 28 years old ranging from 10 to 63 years. Clinical manifestations of 1 familial case were left knee pain and limitation of activity for 3 years, and other 5 cases without clinical manifestation. In 3 sporadic cases, there were 2 males and 1 female with an average age of 33.7 years old ranging from 25 to 44 years. Three sporadic cases had obvious injury history with following up from 6 to 12 months. All imaging results of 9 cases were observed.

RESULTSThe imaging data of 6 familial osteopoikilosis showed the multiple round or oval nodes within bone with clear margins, uniform density, different size. The occurrence of the hyperostotic spots preferentially localized in the epiphyses and metaphyses of the long bones, and carpus and tarus. X-ray features of 3 sporadic osteopoikilosis were similar to that of 6 familial cases and for 6 to 12 months follow-up X-ray features were unchanged.

CONCLUSIONThe imaging features of osteopoikilosis are relatively specific such as the multiple mottling dense focal within bone with clear border and bilateral symmetry, and the focus located on cancellous bone and the diaphyses usually is unaffected. The imaging is a valuable examination for the accurate diagnosis of osteopoikilosis.

Objective: To optimize the decolorization technology of activated carbon for the plant pigment in Bletilla striata polysaccharide.Methods: Using L 9 (3 4) orthogonal test with activated carbon as the decolorizer, the amount of activated carbon, decolorization temperature, decolorization liquid pH and decolorization time were investigated.The decolorization rate and polysaccharide retention rate were investigated.The decolorization rate and polysaccharide retention rate were taken as the indices.Results: The optimum decolorization technology was as follows: the amount of activated carbon was 1.0%, the decolorization temperature was 40 ℃, the pH value was 5 and the decolorization time was 30 min.Under those conditions, the decolorization rate of Bletilla striata polysaccharide was 91.3% and the retention rate of polysaccharide was 80.6%.Conclusion: The selected decolorization technology of activated carbon can make Bletilla striata polysaccharide get the best decolorizing effect.

OBJECTIVE To discuss the clinic presentation,imaging characteristics and surgical management of the external auditory canal cholesteatoma (EACC) with invasion of the tympaniccavity and the mastoid. METHODS This was a retrospective study including the clinical data of 14 cases of EACC invading tympanic cavity and mastoid from 1998 to 2003 . RESULTS All 14 cases showed different bone erosion in the four walls of external auditory canal with extention to the mastoid . Pars flaccida perforation were found in 4 cases with invasion of the cholesteatoma into the tympanic cavity, the ossicular chains were compressed or destroyed. The bony mastoid segment of facial canal was destroyed in 3 cases . Cerebral plate destruction and congenital stenosis of external auditory canal were found in one case respectively. According to the extent of disease, modified radical mastoidectomy was performed in 8 cases and radical mastoidectomy in 5 cases , meatoplasty in one case. The post-operative hearing of 10 cases with intact ossicula chains were normal.One case with compression,shift of ossicules also got normal audition after the operation. The hearing threshold of the air condition in 3 cases with ossicular disruptions got 15 to 20dB of improvement among the language frequency after reconstruction of ossicular chain. The 14 cases were followed-up from 18 months to 5 years and no recurrences were found. CONCLUSION The exact etiology of EACC still remains unclear. There is some difficulty in diagnosing external auditory canal cholesteatoma (EACC) invading the tympanic cavity and the mastoid because of its untypical clinic presentation . High-resolution temporal bone CT scan could help to find out the primary lesion and determine the range of the pathological changes, and choose the proper surgical approach.

Objective To investigate the association between morniing blood pressure surge (MBPS) and carotid atherosclerosis in elder patients with essential hypertension. Methods According to the results of24h ambulatory blood pressure monitoring, 106 patients were classified as the morning BP surge group (MBPS group,n = 58) ,and nonsurge group (NMBPS group, n = 48). Patients underwent carotid ultrasound and the intima-medial thickness (CCA-IMT) and plaques were examined. Results The CCA-IMT of the MBPS group was significantly thicker than that the NMBPS group[(1.27 ± 0. 12)mm vs (0.92 ± 0.33 )mm], P ＜ 0. 05 ) ;②Compared with the NMBPS group,the severity of carotid arteries plaque of the MBPS group was significantly higher (72. 15% vs 54.21% ), ( P ＜0. 01 ) ;③Pearson relation analysis showed CCA-IMT level positively correlated with age (r = 0.288, P ＜ 0.001 ) ,the average of 24h SBP ( r = 0. 768 ,P ＜ 0. 001 ), and MBPS ( r = 0. 768, P ＜ 0.001 ). Conclusion The study showed that MBPS was closely related with carotid atherosclerosis in elder patients with essential hypertension and was an important risk factor in the process of atheresclerosis.
