The clinical values of acetoacetate ( AcAA ) and β hydroxybutyrate ( βHBA ) determination in classification of type 1 and2 diabetes were explored. 102 normal control subjects,33 cases of type 1 diabetes, and 104cases of type 2 diabetes were enrolled. Serum AcAA, βHBA, fasting plasma glucose ( FPG), C-peptide, and insulin levels were measured. The results showed that serum AcAA, βHBA, total ketone tody (TKB) levels in the diabetic groups were significantly higher than those of the normal group( P＜0. 01 ). AcAA, βHBA, TKB levels in type 1diabetes were higher as compared with those of type 2 diabetes( P＜0.01 ). The AcAA, βHBA, and TKB levels were negatively related with C-peptide and insulin in diabetic patients( P＜0. 01 ). All the type 1 diabetic patient were found to have TKB and lower C-peptide levels. TKB positive and lower C-peptide in type 2 diabetes were found in 47% and 26% respectively. Receiver operating characteristic (ROC) curve suggested that the area under the ROC curve of type 1 and type 2 diabetes was 0.926. The optimal operating point of the total ketone body was 0. 532 mmol/L with higher sensitivity and specificity. Enzymatic determination of acetoacetate and β hydroxybutyrate seems to have important clinical values for classification of type 1 and 2 diabetes.

Objective To survey and analyze characteristics of brucellosis epidemic in Weinan city of Shaanxi province for the purpose of setting up prevention and control measures for the disease. Methods According to "The Executing Plan for the Work of Surveying Brucellosis Disease in Shaanxi Province", 35 villages(towns) of designated monitoring locations and 24 villages (towns) of randomized monitoring locations in five countries of Weinan were chosen to survey brucellosis disease. The five countries were Chengcheng, Dali, Heyang, Tongguan and Hancheng. High risk populations with a history of contacting livestock and livestock products aged between 7 and 60 underwent clinical and serology examination[rose bengal plate agglutination test(RBPT) and standard tube agglutination test(SAT)]. All manipulation methods and judging standards were in accord with the "Diagnostic Standard for Brucellosis" (WS 269-2007). Results In the designated monitoring location, a total of 8664 people at high risk were investigated, among whom 1407 people were tested by RBPT test and 27 people were positive,the positive rate was 1.92%(27/1407); 27 people were tested by SAT test and 27 people were positive, the positive rate was 100% (27/27); 25 people were diagnosed and the diagnosis rate was 92.59%(25/27). In the randomized monitoring location, a total of 3464 people at high risk were investigated, among whom 411 people were tested by RBPT test and 3 people were positive, the positive rate was 0.73%(3/411 ), 3 people were tested by SAT test which were all positive and made a definite diagnosis. Twenty-eight new cases were made a definite diagnosis and its incidence was 2.06 in a hundred thousand(28/1 361 618). Conclusions The infection of human brucellosis in Weinan city stays at higher level. The governments should increase input for the monitoring,investigating and disinfecting to prevent the disease from increasing and outspreading.

OBJECTIVETo discuss operative methods and effects for Müller-Weiss disease.

METHODSFrom March 2005 to May 2011, 15 patients were operated. There were 2 males and 13 females, with an average age of 51.8 years (range, 26 to 62 years). The preoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was (42 ± 13) points. According to the Maceira Staging system, 1 foot was grade 2, 6 feet were grade 3, 4 feet were grade 4, and 4 feet were grade 5. The technique consisted of arthrodesis of the talonaviculocuneiform joints with plate, arthrodesis of the talonavicular joint and arthrorisis of naviculocuneiform joint with plate, or triple arthrodesis with screws, according to the preoperative evaluation.

RESULTSTen feet were treated with arthrodesis of the talonaviculocuneiform joints, 3 feet were treated with arthrodesis of the talonavicular joint and arthrorisis of naviculocuneiform joint and 2 feet were treated with triple arthrodesis. Two patients were lost to follow-up. The average follow-up after operation was 19.2 months (range, 9 to 38 months). All feet were solid fusion and the average duration of union was 13.3 weeks (range, 12-16 weeks). The AOFAS ankle-hindfoot score at the last follow-up was (83 ± 6) points. Two feet were excellent, 10 feet were good, and 1 foot was fair. The length of feet was (14.2 ± 1.0) cm before surgery and (15.7 ± 0.9) cm at the last follow-up (t = 11.570, P < 0.05). The Meary's angle was -6.1° ± 13.1°before surgery and 1.1° ± 3.0° at the last follow-up (t = 2.248, P < 0.05). The talocalcaneal angle was 4.5° ± 2.2° before surgery and 18.0° ± 4.0° at the last follow-up (t = 11.700, P < 0.05). One foot had breakage of the plate and screws at arthrorisis of naviculocuneiform joint and none had complications related to the incision.

CONCLUSIONOperations for Müller-Weiss disease, according to concrete conditions using different therapeutic program, may achieve a satisfactory outcome.

Objective To evaluate the role of nutritional parameters in prognosis,especially in the early and late mortality of hospital-acquired acute kidney injury (AKI) patients.Methods This study was a prospective cohort study conducted in a hospital comprising 1500 beds in Shanghai, China. One hundred ninety-four patients with hospital-acquired AKI, as determined using the RIFLE staging criteria,were enrolled as subjects after obtaining informed consent.Patients with AKI caused by postrenal obstruction,glomerulonephritis,interstitial nephritis or vasculitis were excluded.Nutritional evaluation,including subjective global assessment (SGA),anthropometric and laboratory examination,was conducted. Other laboratory measurements and clinical data were recorded.The primary outcome was early mortality (≤ 7 days) and late mortality (8-28 days) after enrolling into the study. Results AKI patients at enrollment were characterized by a high prevalence of malnutrition as determined by SGA, anthropometric and laboratory examination.Univariate analysis showed that the SGA,the serum levels of prealbumin,cholesterol and total lymphatic cells, and the Maastricht index were significantly different among early mortality,late mortality and survival groups.The serum prealbumin and cholesterol levels in the early death group were significantly lower than those in the survival and late death groups (P＜0.05).Multivariate analysis revealed that SGA,albumin,prealbumin and cholesterol remained independently and significantly associated with early mortality after adjusting for age,sex,dialysis,ventilation,hemoglobin,platelets,bilirubin,and Glasgow coma score.The areas under the receiver operating characteristic curve to predict early mortality for albumin,prealbumin and cholesterol were 0.591,0.736 and 0.603,respectively,with that of prealbumin significantly higher than others (P＜0.05). Conclusion Low levels of serum prealbumin,albumin and cholesterol at enrollment are independtly associated with increased early mortality in hospital-acquired AKI patients.

Saliva and blood were collected from two patients who had not received post exposure prophylaxis in the cities of Wenzhou and Xinning respectively. Both patients were confirmed as positive for rabies by detection of rabies virus specific nucleoprotein antibodies in the sera by Western Blot. However, rabies virus specific RNA was only identified in the saliva collected from the patient in Wenzhou. Furthermore, the isolate Zhejiang Wz0 (H) was obtained by inoculating one-day-old suckling mice. Both nucleoprotein (N) and glycoprotein (G) genes from the isolate were amplified by RT-PCR and sequenced. Phylogenetic analysis indicated that the isolate belonged to classic rabies virus, and shared a higher homology with the street viruses from dogs in the main endemic areas in China and the street virus from dogs in Indonesia than with other known strains. Further comparison of the deduced amino acid sequences between the isolate and the vaccine strains used in China showed that the virus had a higher level of homology with the vaccine strain CTN than with the other vaccine strains (3aG, PV, PM and ERA). In particular, amino acid residues substitutions located in antigenic site Ⅲ in the G protein, which could react with the neutralizing antibodies, were observed. These results suggested that the virus belonged to the classic rabies virus, and both N and G genes diverged from the current vaccine strains used in China at either the nucleotide or the amino acid level.

OBJECTIVETo investigate whether CYC116 can potentiate matrine-dependent growth inhibition and apoptosis in multiple myeloma (MM) cells.

METHODSThe dose response relationship of matrine to dexamethasone-resistant and dexamethasone-sensitive MM cells was first established. Myeloma RPMI8226 cells were treated with matrine alone or combined with CYC116 for 24 h. Cell proliferation was measured using an MTT assay and apoptosis induction was evaluated by flow cytometry. Activation of the caspase pathway and expression of apoptosis regulator proteins were detected by Western blotting.

RESULTSMatrine significantly induced growth arrest and apoptosis in both drug-resistant and drug-sensitive MM cells. Treatment with the combination of matrine and CYC116 had a stronger cytotoxic effect on MM cells than did single drug treatments. Enhanced apoptosis observed following the combined treatment of matrine and CYC116 was associated with higher levels of activation of caspase-9, caspase-3, and poly adenosine diphosphate ribose polymerase (PARP) and down-regulation of the anti-apoptotic proteins Bcl-2 and Mcl-1 and the signaling proteins p-Akt and nuclear factor κB (NF-κB).

CONCLUSIONCYC116 enhances the growth inhibitory and apoptotic effects of matrine on MM cells.

Objective: To compare aortic annular diameter measured by transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), and multislice computed tomography (MSCT) in patients with severe aortic stenosis, and to evaluate the impact on selection of prosthetic valve type in transcatheter aortic valve implantation (TAVI). Methods: Clinical data of 138 patients with severe aortic stenosis referred for TAVI between January 2014 and June 2016 in our hospital were retrospectively analyzed.The difference of aortic annular diameter measured by TTE, TEE, and MSCT were compared.TTE was performed after TAVI to evaluate the accuracy of measurement before TAVI. Results: (1) Aortic annular diameter was (23.37±2.22) mm by TTE and (23.52±1.70) mm by TEE (P=0.12). Pearson correlation analysis showed that aortic annular diameter measured by TTE was correlated to that measured by TEE (r=0.87, P<0.05). (2)The long-axis diameter and the short-axis diameter measured by MSCT multiplanar reconstruction were significantly different ((27.86±2.87) mm vs. (21.91±2.53) mm, P<0.05). There was no significant difference between the mean of the long- and short-axis diameters and the diameter derived from cross-sectional area by MSCT ((24.92±2.38) mm vs. (24.84±2.25) mm, P=0.08). However, the diameter derived from the circumference ((25.35±2.34) mm) was significantly larger than the mean of the long- and short-axis diameters and the diameter derived from cross-sectional area by MSCT, and the difference were (0.43±0.62) mm and (0.51±0.62) mm respectively(both P<0.05). (3) Measurements of the aortic annulus diameter by MSCT including the mean of the long- and short-axis diameters, diameter derived from cross-sectional area, and diameter derived from the circumference were larger than the measurement by TTE and TTE (all P<0.05). (4) Implantation was successful in all patients.Moderate to severe paravalvular leakage was detected in 3 patients at 7 days post TAVI, and 1 patient developed severe prosthetic valve restenosis at 6 months post TAVI and received valve-in-valve implantation. Conclusions In severe aortic stenosis patients referred for TAVI, the aortic annular diameter derived from TTE and TEE measurements are smaller than that from MSCT.In the absence of a gold standard, selection of prosthetic valve type in TAVI procedure should rely on comprehensive considerations, which is of importance to get good clinical results for severe aortic stenosis patients underwent TAVI.

Objective To investigate the application of self-made multi-functional connectors for oxygen bags in emergency nursing.Methods Totals of 80 nurses from Emergency Department and Service Department were trained by a research group on using multi-functional connector for oxygen bags.Self-contrast method was used:a nurse used traditional method to supply and balloon oxygen as well as seal the bag mouth (80 times for the control method),and then use self-made multi-functional connectors for the same progress (80 times for the experimental method).Self-designed questionnaire was used to investigate and compare two methods.Results 98％ nurses were qualified by training only once.Operating time of the experimental group (24.51 ± 5.33)seconds was obviously shorter than that of the control group (242.82 ± 9.21)seconds and the difference was statistically significant (t =29.77,P ＜0.01).According to the results of questionnaires,the satisfaction on the acceptance,handle ability and oxygen leakproofness of the multi-functional connector was more than 95％,and the satisfaction on connection tightness,reduction of workload and improvement of work efficiency reached 100％.Conclusions Self-made multi-functional connector for oxygen bags is simple to operate,and can effectively reduce nurses' workload and improve nursing satisfaction.
