OBJECTIVE: To study the feasibility of quantitative analysis of multi-components by single-marker (QAMS) in determination of flavones in Shuanghuanglian preparations by comparing the results assayed by QAMS and external standard method (ESM). METHODS: The analysis was performed on a Xtimate™ C18 column (4.6 mm × 250 mm, 5 μm)with methanol and water containing 0.2% phosphoric acid as the mobile phase in gradient elution. The flow rate was set at 1.0 mL · min-1. The UV detector wavelength was 274 nm, and the column temperature was 30°C. RESULTS: Within the linear ranges, the analysis results showed no significant difference between QAMS and ESM. CONCLUSION: The QAMS method is credible and will be a new quality evaluation pattern for the determination of multiple flavones in Shuanghuanglian preparations.

ObjectiveTo study the effect of early rehabilitation on disability of motion and cognition.Methods107 patients were randomly divided into two groups,rehabilitation group (51 cases) and control group (56 cases).Patients in rehabilitation group were given regular early rehabilitation,while all patients in both groups were given usual clinical treatment. The Barthel Index (BI), Fugl-Meyer Assessment (FMA), Mini-mental Status Examination (MMSE) were used to evaluate these two groups before and 3 months after treatment. ResultsAfter treatment, the scores of BI, FMA and MMSE were improved significantly(P<0.05) in rehabilitation group compared with that before treatment, so did that of BI, FMA in control group(P<0.05).The scores of BI、FMMS、MMSE in rehabilitation group improved significantly compared with that in control group(P<0.05).ConclusionEarly rehabilitation may obviously improve the motive and cognitive function and increase the quality of living of hemiplegia after stroke.

Objective To learn the existing state of Keshan disease and its trend in Baoji City,and to provide a scientific basis for control of the disease.Methods Feng,Qianyang,Linyou and Long Counties,the Keshan disease affected areas were selected to carry out the case study,and Keshan cases were searched from all registered cases of myocardial patients of the past three years at county-level medical institutions and hospitals of townships(towns).Thirteen villages affected by Keshan disease in Qianyang,Fengxiang,Feng,Linyou and Long Counties were selected as monitoring points to carry out a intensified monitoring.All subjects were surveyed by comprehensive clinical physical examination and 12-lead ECG tracings,and they were diagnosed according to the Keshan disease diagnostic criteria.Ten households were selected randomly in each monitoring point(village),and self-produced wheat samples and adult subject's occipital hair samples were collected for detecting selenium levels.Results Seven hundred and forty-six cardiac cases which containing 17 cases of chronic Keshan disease were discovered in 32 medical institutions,and there were no acute and subacute type of Keshan disease patients.Five thousand seven hundred and twenty-three subjects were examined in the 13 monitoring sites,and 65 cases of Keshan disease were diagnosed which including 17 cases of slow and 48 cases of potential Keshan disease,and no acute or subacute case was found.The total detection rate was 1.14％,and the detection rate ranged from 0 to 2.86％.Hair selenium mean was 0.420 mg/kg; wheat selenium mean was 0.079 mg/kg.Conclusions The Keshan disease detection rate of Baoji City is at a low level.The selenium level of local residents has reached the level of non-endemic area.Constant detection of patient with Keshan disease means various control measures should be reinforced.The comprehensive monitoring program,such as monitoring people's in vivo and in vitro selenium level and others,should be established as soon as possible.

Objective: To learn the health literacy status, trend and associated factors of Ningbo residents from 2015 to 2019, so as to provide basis for developing health policies and interventions. Methods: The monitoring data of health literacy of Ningbo residents from 2015 to 2019 was collected. The health literacy level was calculated and standardized by the population data of the sixth national census of Ningbo in 2010; five-year absolute growth and growth rate were used to reflect the changing trend. Multivariate logistic regression model was employed to analyze the influencing factors for the health literacy level. Results: The health literacy levels from 2015 to 2019 were 15.44%, 21.73%, 22.41%, 27.60% and 30.03%, with an annual increase trend ( P<0.05 ). The five-year absolute growth and growth rate were 14.59% and 94.49%. The Results of multivariate logistic regression analysis indicated that the year ( OR=1.158, 95%CI: 1.132-1.184 ), age ( 25-<35岁 years, OR=1.235, 95%CI: 1.039-1.468; 35-<45岁 years, OR=1.416, 95%CI: 1.193-1.681; 45-<55岁 years, OR=1.221, 95%CI: 1.024-1.455 ) , education level ( primary school, OR=1.790, 95%CI: 1.461-2.195; junior high school, OR=2.574, 95%CI: 2.102-3.154; high school/vocational high school/technical secondary school, OR=4.863, 95%CI: 3.943-5.998; college or above, OR=8.829, 95%CI: 7.109-10.965 ) , urban areas ( OR=0.934, 95%CI: 0.874-0.998 ) and occupation ( farmers, OR=0.692, 95%CI: 0.608-0.787; workers, OR=0.746, 95%CI: 0.664-0.837; enterprise staff, OR=0.822, 95%CI: 0.745-0.906; others, OR=1.106, 95%CI: 1.009-1.211 ) were the influencing factors for health literacy level. Conclusion The health literacy level of Ningbo residents shows an upward trend from 2015 to 2019, which are associated with age, education level, area and occupation.

[Summary] According to the cutpoint of plasma triglycerides concentration ≥ 1.7 mmol/L,waist circumference ≥85 cm in men or ≥80 cm in women,459 patiens with type 2 diabetes mellitus were divided into four groups:normal waist circumference and triglycerides,normal waist circumference and hypertriglyceridemia,abdominal obesity and normal triglycerides,and hypertriglyceridemic-waist (HTWC) group.The results showed that body mass index,waist circumference,systolic blood pressure,triglycerides,microalbuminuria,and homeostasis model assessment insulin resistance index (HOMA-IR) in HTWC group were higher than those in non-HTWC groups (all P＜0.01),as well as higher diabetic nephropathy incidence (P＜0.05).Multiple logistic regression analysis revealed that HTWC was an independent risk factor of diabetic nephropathy (OR =2.070,95 ％ CI 1.195-3.586).

Objective To investigate the dynamic changes of chromogranin A in patients with pancreatic neuroendocrine neoplasms after laparoscopic surgery,and to monitor the diagnosis and prognosis of patients with real-time monitoring.Methods Forty-five patients with pancreatic neuroendocrine neoplasms were enrolled in this study from March 2013 to March 2015 in First Hospita of Yulin City.All patients were underwent laparoscopic surgery.The surgical results were observed and the levels of postoperative chromogranin A were monitored.Comparisons between groups were evaluated with the x2 test.Follow-up using telephone interview was performed to detect patients' survival and up to January 2017.Results TNM patients with benign and malignant patients in the postoperative chromogranin A examination found that the positive expression rate were 85.0％ and 53.0％,the difference between the two groups was statistically significant (P ＜ 0.01) and the corresponding synaptophysine examination were 88.0％ and 89.0％ (P ＜ 0.05).The positive expression rates of chromogranin A in patients with lymph node metastasis and non-lymph node metastasis were 47.0％ and 80.0％,respectively (P ＜ 0.01).The positive expression rates of the corresponding synaptophysin were 87.0％ and 87.0％,respectively (P ＞ 0.05).Conclusion Endoscopic surgery for pancreatic neuroendocrine neoplasms is a minimally invasive,safe surgical approach,long-term survival rate of patients with the use of chromogranin A to monitor the level of patients after surgery can effectively assess the development and prognosis of the disease,but the synaptophysine has no significance in assessing the prognosis of the patient.

Objective To investigate the expression and significance of myeloid cell leukemia-1 (Mcl-1 )gene and protein in Hepatocellular Carcinoma(HCC).Methods The expression of Mcl-1 was detected respectively by Reverse Transcription-Polymerase Chain Reaction (RT-PCR),Western blot and ENVISION immunohistochemistry in 20 HCC specimens,19 liver cirrhosis(LC)specimens,and 12 control ones.Their relationship with clinical and pathological characteristics of HCC was investigated.Results The expression of Mcl-1 mRNA in the control group,LC group and HCC group was 0.52±0.17, 3.46±1.7,3.65±2.93,respectively.The level in HCC and LC group was statistically different compared with the control group,respectively (t=7.925,5.334,P<0.05).The relative expression of Mcl-1 protein in LC group (0.51±0.35)and HCC group (0.75±0.36)were significantly higher than that in the control group (0.21±0.19)(t=5.526,6.355,P<0.05).The positive expression rate of Mcl-1 in HCC group was 55.00% (11/20),significantly higher than that in the con-trol group 33.33% (4/12)(t=7.835,P<0.05).The positive expression of Mcl-1 was related to tumor necrosis and TNM staging (χ2=4.201,P<0.05).Conclusion Mcl-1 gene and protein are differentially expressed in HCC,LC and the control, which may be involved in the occurrence,development and malignant transformation of HCC.

Objective: To study the fluid distribution abnormalities in patients on hemodialysis and fluid shift between intracellular and extracellular compartment during hemodialysis (HD).Methods: Eighty stable end stage renal disease patients on maintenance hemodialysis were selected. Conventional low flux dialyses at dialysate sodium concentration of 138 mmoL/L were performed for all of the patients. Fresenius polysulphons or Gambro hemophon dialyzers were used. All of the patients showed no clinical signs of over ultrafiltration during HD sessions and dry body weights were considered adequate. Intracellular water (ICW), extracellular water (ECW) and total body water (TBW) were measured and standardized by body weight (nICW, nECW, nTBW) before and after HD sessions. Sixty-seven cases of sex, age and body weight matched normal individuals were used as controls. Bio-impedance spectrum (BIS) analysis (Xitron, Technolo gies, San Diego, CA, USA) was used in body fluid measurement. Pre and post HD nICW, nECW, and nTBW were compared with these of the controls.Results: There were no differences in age, post-dialysis body weight and body mass index between patients on hemodialysis and the controls. Patients on hemodialysis had less nICW [male (0.28?0.05) vs (0.33?0.04), P
