Objective To investigate the decreasing pattern of activities of daily living (ADL) in patients with dementia. Methods A total of 204 patients with dementia were collected,among which 106 cases were with Alzheimer's diseases(AD),54 cases with vascular dementia(VD),44 cases with other types of dementia.According to the scores of mini-mental state examination(MMSE),mild,moderate and severe dementia were 42 cases,37 cases and 125 cases,respectively.All of them were assessed by Barthel index(BI) and compared among degrees of dementia,between AD and VD,and levels of education. Results The most reserved items were bowel movement (48.5 ％),urination (44.1 ％) and grooming (40.2％),while the most vulnerable items were climbing stairs (25.5％) and bathing(18.1％).With increasing impairment of cognition,the scores of BI were getting decreasing. There were significant differences among severe [(23.20 ± 29.27)scores],moderate[(65.54 ± 26.35) scores] and mild [(87.38 ± 22.69) scores] groups (x2 =99.686,P =0.000). Basic ADL were more reserved in AD (16.98％-53.77％) compared with VD (1.85％-33.33％) patients.No significant differences were found(x2 =3.653,P=0.161)among patients with education of primary school and below [(40.1 ± 39.0) scores],middle school[(45.3 ± 39.6 ) scores],and high school and above[(53.1 ± 37.7) scores]. Conclusions Among patients with dementia,bowel control,bladder control and grooming are well reserved,climbing stairs and bathing are vulnerable functions.Basic activities of daily living may be affected by cognitive status and the types of dementia but not levels of culture.

ObjectiveTo explore the role of β-catenin in the proinvasive consequences of hypoxia in hepatocellular carcinoma (HCC).MethodsWe established in vitro and in vivo hypoxic models using the highly metastatic MHCC97 and the stable red fluorescent protein-expressing MHCC97-R cells.The role of β-catenin in hypoxia-mediated aggressiveness was investigated by β-catenin knockdown.ResultsHypoxia caused a pronounced arrest of proliferation in MHCC97 cells,suppressed tumor growth in MHCC97-R xenografts,but promoted in vitro invasiveness and in vivo metastasis.β-Catenin-silencing by short hairpin significantly inhibited the enhanced invasiveness of MHCC97 cells due to hypoxia,reduced the increase in distant metastasis by hepatic arterial ligation,but failed to further restrain cell proliferation.Conclusionβ-Catenin in HCC cells plays an essential role in the hypoxia-induced metastatic potential.A reduction of βcatenin expression inhibited the proinvasive consequences of hypoxia in HCC.

Objective: To explore the cognitive level and the mental status of the patients suffering from perimenopausal syndrome in Shanghai, and to identify the traditional Chinese medicine syndrome distribution feature of perimenopausal syndrome. Methods: The cognitive level of the perimenopausal women was evaluated by using general living problem questionnaire. The mental status of the perimenopausal women was evaluated by using self-rating depressive scale. The traditional Chinese medicine syndrome distribution feature of perimenopausal syndrome was identified by using traditional Chinese medical symptoms questionnaire. Results: A total of 634 perimenopausal women finished the investigation. There were 74.76% (474/634) patients who knew little about the perimenopausal syndrome; 77.29% (490/634) patients had a depressive tendency; 8.36% (53/634) patients had depressive disorder. There were 72.40% (459/634) patients who had the symptoms such as susceptibility to anger and restlessness, restless sleep at night, thirst with dry throat and bitter taste, and all these symptoms could be classified into hyperactivity of heart and liver fire syndrome. Conclusion: Patients suffering from perimenopausal syndrome know little about this disease and mostly have depressive tendency, and the major traditional Chinese medicine syndrome pattern is hyperactivity of heart and liver fire based on the chief clinical manifestations of the patients.

Objective To study the role of preoperative CA19-9 level in predicting resectability of pancreatic cancer.Methods Preoperative CA19-9 levels were determined by radioimmunoassay.The receiver operating characteristic curve was used to determine the cut-off point.The clinical value of the level of CA19-9 as a predictive marker of resectability was evaluated by the area under curve.Results The preoperative CA19-9 levels in the resectahle group was (313.6±515.5) kU/L,which was significantly lower than (852.1± 865.1)kU/L in the unresectable group (P＜0.001).The cut-off point of CA19-9 for predicting pancreatic cancer resectability was 312.1 kU/L,which had a sensitivity of 56.6％ and a specificity of 73.3％.The area under curve was 0.67.Conclusions The preoperative CA19-9 level may be used to predict resectability of pancreatic cancer.

Pancreatic neuroendocrine tumor is a common pancreatic tumor with high heterogeneity and multiple management modalities. A standard and practical staging system for pancreatic neuroendocrine tumors will be beneficial to clinical management and research. At present, there are two staging systems (ENETS and AJCC). Both of them have shortcomings which limit their clinical application. In addition, the coexistence of two staging systems is confusing to clinicians. We proposed a modified ENETS staging system by keeping the ENETS TNM definition and adopting the AJCC staging definition. The modified staging system can successfully distinguish patients with different prognosis and is helpful in establishing clinical standard. This study has been published in Journal of Clinical Oncology (JCO) and was selected as 2017 Best of JCO: Gastrointestinal edition. This paper was aimed to interpret the modified staging system in clinical practice.

Objective Despite regular treatment,antineutrophil eytoplasmie antibodies(ANCA)asso- ciated systemic vasculitis(AASV),in which the role of Fc?Rs has been established,are still associated with significant long-term mortality and remain an important cause of end-stage renal failure.ANCA plays an im- portant role in the pathogenisis of primary systemic small vessel vasculitis(PSV)by their potential to activate neutrophils.Because the interaction between ANCA and its receptors on the Fc portion of immunoglobulins (Fc?R)on neutrophils is essential in the activation process,we investigate the inhibitory,effect of tg19320 on ANCA induced activation of neutrophils,which is a tetrameric tripeptide that interferes with IgG/Fe?Rs in- teraction.Methods We prepared tg19320 by solid-phase peptide syntbesis.The binding between tg19320 and human IgG was assessed by enzyme-linked immunosorbent assay.The biological activity of tg19320 to intefere with FcF?receptor recognition was identified by rosette formation assay.ANCA IgG was prepared from the sera of active Wegener's granulomatosis(WG)and microscopic polyangiitis(MPA)patients.Neu- trophils isolated from the blood of healthy volunteers were primed with TNF-?(2 ng/ml)and then incubated with ANCA IgG(200?g/ml),or pretreated with tg19320(2.5 mg/ml)and then added with ANCA IgG.Su- peroxide burst of neutrophils was determined by Ferri-cytochrome reduction assay.Results We found that tg19320 bound tightly to human IgG in a dose dependent manner and the inhibition of the rosette formation between SRBC-IgG and U937 cells was statistically significant(20.3% vs 53.2%,P

Objective: To examine the association between serum vitamin D level and thyroid function indicators among elderly patients with type 2 diabetes mellitus (T2DM), so as to provide the evidence for the prevention and treatment of thyroid function abnormality among elderly patients with T2DM. Methods: Inpatients aged 60 years and older and admitted to the department of endocrinology of Zhejiang Hospital were selected as the study subjects. Gender, age, course of disease and other basic information were collected through questionnaire surveys. The serum 25-hydroxyvitamin D[25-(OH) D], thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), total triiodothyronine (TT3), and total thyroxine (TT4) were measured. The correlation between serum vitamin D level and thyroid function indicators in elderly patients with T2DM was evaluated by a multiple linear regression model. Results: A total of 402 elderly patients with T2DM were surveyed, including 210 males (52.24%) and 192 females (47.76%), and had a median age of 70.00 (interquartile range, 12.00) years and a median course of disease of 14.00 (interquartile range, 14.00) years. There were 162 patients with insufficiency of vitamin D (40.30%) and 182 patients with deficiency (45.27%). The levels of TSH and glycated hemoglobin in the vitamin D deficiency group were (2.34±1.66) μIU/mL and (8.83±2.14) %, respectively, which were higher than those in the normal group [(1.74±1.10) μIU/mL and (8.11±1.75) %; P<0.05]. The levels of FT3 and FT3/FT4 in the vitamin D deficiency group were (2.86±0.48) μIU/mL and 2.85±0.71, respectively, which were lower than those in the vitamin D insufficiency group [(3.09±0.47) pg/mL and 3.14±0.81, P<0.05]. Multiple linear regression analysis showed a negative correlation between 25- (OH) D and TSH (β'=-0.159, P=0.001). Conclusion The vitamin D deficiency may be associated with the increase of TSH level among the elderly patients with T2DM.

OBJECTIVETo investigate the protective effect of Danxuetong injection (DXT, a combination of Danshen and Xueshuantong injections) against testicular ischemia-reperfusion injury following testis torsion/detorsion in rats.

METHODSThirty-two 4-week-old healthy male SD rats were randomly divided into four groups of equal number: sham operation, normal saline, single DXT injection, and successive DXT injection. The rat models of testicular ischemia-reperfusion injury were established by 2-hour 720-degree torsion/detorsion of the unilateral testis. At 6 weeks after modeling, the rats were killed and their testes were harvested for measure- ment of testicular coefficients, sperm counts, sperm motility, and the levels of total anti-oxidative capacity (T-AOC) , superoxide dismutase (SOD) , nitric oxide synthase (NOS) , and malondialdehyde ( MDA) in the testis tissue.

RESULTSCompared with the rats of the normal saline group, those of the single DXT injection and successive DXT injection groups showed significant increases in the testicular coefficient (0.11 ± 0.03 vs 0.35 ± 0.04 and 0.40 ± 0.06, P < 0.05), sperm count ([0.46 ± 0.10] vs [1.44 ± 0.50] and [3.00 ± 1.28] x10(9)/ml, P < 0.05), sperm motility ([13.63 ± 14.04] vs [39.63 ± 5.04] and [76.31 ± 3.67]%, P < 0.05), the activity of SOD (72.76 ± 5.58 vs 116.25 ± 8.83 and 133.20 ± 13.84, P < 0.05), and the level of T-AOC (5.58 ± 1.07 vs 13.34 ± 5.81 and 19.21 ± 5.69, P < 0.05), but a remarkable decrease in the content of MDA (42.38 ± 8.94 vs 20.94 ± 5.65 and 15.02 ± 1.03, P < 0. 05) in the injured testes.

CONCLUSIONDXT can effectively rid the testis tissue of oxygen free radicals, improve sperm count and motility by antioxidation, and protect the testis tissue of prepubertal rats against testicular ischemia-reperfusion injury after testis torsion/detorsion. It also has a protective effect on the contralateral testis, and successive injection has a better effect than single injection of DXT.

Objective To evaluate the pattern of energy metabolism and nutrients intake in patients with chronic viral hepatitis and posthepatitic cirrhosis to effectively direct their nutrition therapy.Methods Resting energy expenditure (REE) was measured with open-circuit indirect Jorimetry in 60 patients with chronic viral hepatitis and 60 patients with posthepatitic cirrhosis.Their normal basal energy expenditure (BEE) was predicted by Harris-Benedict equation and energy intake (EI) was determined by diet recall. Correlation between REE and indicators for nutrition assessment was analyzed.Results REE was (77? 21) kJ?kg~(-1)?d~(-1) in 60 patients with pusthepatitic cirrhosis,significantly lower than BEE[(95?16) kJ? kg~(-1)?d~(-1)(P0.05,and their EI was (127?34) kJ?kg~(-1)?d~(-1),1.41?0.43 times as REE,in which PROI was (1.02?0.29) g?kg~(-1)?d~(-1),1.31?0.61 times as PROE (0.87?0.34) g?kg~(-1)?d~(-1),also indicating a negative nitrogen balance (-2.02?4.07).REE,EI and intake of three nutrients,serum level of albumin and prealbumin (PA) and body weight significantly decreased in patients with posthepatitic cirrhosis,as compared to those in patients with chronic viral hepatitis (P

Objective To detect the lymph node micrometastasis in resected pancreatic head carcinoma, to investigate the role of lymphatic micrometastasis in clinical staging and predicting prognosis of the pancreatic head carcinoma. Methods Pancreaticoduodenectomy with extended lymph nodes dissection were performed in 20 patients with pancreatic head carcinoma. All the lymph nodes were taken out by operating microscope method and metastasis was diagnosed by routine histological examination with hematoxylin and eosin staining, and the presence of lymph node micrometastasis was examined by immunohistochemisty. Results A total of 677 lymph nodes were found in the 20 eases, routine histological examination revealed metastasis occurred in 87 lymph nodes in 13 cases. Of the 590 negative lymph nodes by routine histological examination, 57 lymph nodes in 3 cases were diagnosed as having micrometastasis by immunohistochemisty. With the combination of routine histological examination and immunohistochemisty, the percent of patients with positive lymph nodes increased from 65% (13/20) to 80% (16/20), the detection rate of metastasis lymph node increased from 12.9% (87/677) to 21.3% (144/677) with significant difference (P <0.05). The detection of lymph node micrometastasis changed the staging of Ⅱ A to Ⅱ B in 3 patients. Tumor metastasis and recurrence rate of patients with lymph nodes micrometastasis within one year after operation was 75%, while it was 25% of patients without lymph nodes micrometastasis. Conclusions The detection of lymph node mierometastasis metastasis was helpful in the determination of clinical staging and predication of prognosis.
