Objective To discuss the influence of distribution of nursing human resource in maternalinfant wards on patients'satisfaction degree.Methods To analyze the satisfaction degree with nursing quality of all patients and distribution of nursing human resource in maternal-infant wards in our hospital in 2007.Results There was a positive correlation between inpatients'satisfaction of nursing service and distribution of nurses.Theinsufficiency of distribution of nursing human resource in maternal-infant wards caused nurses' sensation of work tiredness,degradation of service quality,bad service attitude,indifference to patients,lack of detail service,insufficiency of basic nursing care,simplistic health education,and unwarranted quality of technique operation.Conclusions The distribution of nursing human resource in maternal-infant wards should be hisher than that in common wards and We should pay attention to the distribution of naming safety in maternal-in-fant wards,increase nurse staffing,rationally utilize human resource,enhance training of comprehensive quality of nurses,strengthen quality awareness,service awareness and safety awareness,ensure the nursing quality and mother-infant safety,and improve patients'satisfaction.

ObjectiveTo evaluate the applicable value of attitude control system combined with attitude controllable intelligent capsule endoscope for stomach examination.MethodsA total of 15 patients were recruited to the study.Manipulability of movement and posture change of capsule endoscope,diagnostic efficacy for such locations as gastric cavity,bulb and descending duodenum,image quality and patients'compliance were assessed.ResultsThe procedure was completed in 14 patients.One failed due to downfall of the endoscope to duodenum within 5 min. Mean operation time was ( 23.7 ± 6.5 ) min ( from 5 to 30 min).Ten cases of superficial gastritis,one case of superficial gastritis with bile regurgitation and 1 case of ulceration of the duodenal bulb were diagnosed.No abnormalities were found in 3 others.Endoscopic images were of high quality and only a few were influenced by gastrointestinal peristalsis.All patients showed compliance with no discomfort.Capsule endoscopes were discharged within 2 or 3 days.ConclusionAttitude control system combined with attitude controllable intelligent capsule endoscope in stomach examination is feasible and valuable in clinic.

A 22-year-old patient was admitted to the hospital with a solitary,gradually growing and painless mass in the left shoulder for 2 years.Physical examination revealed no abnormality except for the skin lesion.Skin examination showed an elevated lesion measuring about 3.5 cm× 2.0 cm × 1.5 cm with smooth surface and normal color,which was located in the subcutaeous tissue,indurated and movable.Resection of the tumor was performed under local anesthesia.On visual observation during operation,the tumor was sited in the subcutaneous fat tissue,nodular-like and surrounded locally by fibrous pseudocapsules with a grey incisal surface and mild texture.Microscopicalty,the tumor was extremely similar to breast fibroadenoma with multiple lobuli,and each of the lobuli was composed of tubiform structures,basal cell-like epithelial cell trabs and fibromyxoid stroma abundant in fibroblast-like spindle cells.No hair bulb or primitive dermal papillae were observed in the lobuli,which were separated by compact collagen fibers infiltrated by a few scattered inflammatory cells.Fibromyxoid strotma was surrounded by basal cell-like epithelial cell strabs in most lobuli,and some tubiform structures were filled with a little thin lightly eosinophilic material in a concentric arrangement.Immunohistochemistry showed that intralobular epithelial cells were strongly positive for cytokeratin 5/6,but negative for CAM5.2 or carcinoembryonic antigen (CEA).In addition,the lightly eosinophilic material in lumens was negative for periodic acid-Schiff (PAS) staining.These results suggested that the tubiform structures were immature follicles,but not sweat ducts.The patient was diagnosed with nodular fibrofolliculoma (NFF) based on the clinical manifestations,morphological features,immunohistochemical and PAS staining results.No relapse was observed in more than 3 months of postoperative follow-up.As a benign trichogenic adnexal neoplasm with unique clinicopathological manifestations,NFF may be a new entity of cutaneous adnexal neoplasm.

Objective To evaluate the predictive value of admission blood glucose level for the mortality within 30-day and major adverse cardiac events(MACE) rate in patients with ST-segment elevation acute myocardial infarction (STEMI). Methods An observational analysis of 7446 Chinese STEMI patients from a global randomized controlled trials of cases recruited within 12 hours of symptom onset was carried out. According to the levels of admission glucose (hyperglycemia was defined as admission glucose>10 mmol/L) and known diagnosis of diabetes mellitus (DM) ,these patients were divided into four groups, Ⅰ :no DM and normal glucose group (control group) ; Ⅱ : DM but normal glucose group; Ⅲ : no DM and hyperglycemia group; and Ⅳ: DM and hyperglycemia group. Results Admission hyperglycemia was associated with a significantly higher 30-day mortality rate (group Ⅲ 17. 1% vs group I 8.6%, group Ⅳ 18.6% vs group Ⅰ 8. 6%, P<0.001) and also an increased incidence of MACE (group Ⅲ36. 3% vs group Ⅰ 21.6%, group Ⅳ 38. 8% vs group Ⅰ 21.6%, P<0.001). However, DM without admission hyperglycemia did not increase the 30-day mortality (group Ⅱ 11.6% vs group Ⅰ 8. 6%, P = 0.096). Multivariate logistic regression analysis showed that compared with group Ⅰ patients, group Ⅲ and group Ⅳ had a risk of death of 1.51 fold(OR 1.51,95% CI 1.22-1.87,P<0.001) and 1.83 fold(OR 1.83,95% CI 1.40-2. 39, P<0.001) respectively; hyperglycemia was an independent predictor of 30-day mortality and an increase of 1 mmol/L in glucose level was associated with a 5% increase of mortality risk (OR 1.05,95% CI 1.04-1.07,P<0.001), but DM without hyperglycemia was not so (OR 1.11,95% CI 0. 87-1.42, P =0. 412). Conclusions The rates of 30-day mortality and cardiovascular events are significantly higher in STEMI patients with acute hyperglycemia than in patients without. Hyperglycemia on admission is an independent risk factor for the short-term outcome of STEMI, but diabetes mellitus without hyperglycemia isv not associated with the short-term mortality.

Objective: To explore the relationship between serum sodium level and early prognosis in patients with acute ST-elevation myocardial infarction (STEMI). Methods: A total of 7461 STEMI patients within 12h of onset who matched the diagnostic standard of European society of cardiology and American college of cardiology were retrospectively studied. According to serum sodium levels within 24h of admission, the patients were categorized into 3 groups: Serum sodium≥135 mmol/L group, Serum sodium 130-134 mmol/L group and Serum sodium<130 mmol/L group. The baseline condition, 30-day mortality with other adverse events and the effect of neuroendocriology inhibitor treatment were compared among 3 groups; their relationships to serum sodium level were analyzed. Results: Serum sodium<130 mmol/L group had the higher 7-day and 30-day mortality than the other 2 groups, both P<0.001; compared with Serum sodium≥135 mmol/L group, Serum sodium<130 mmol/L group presented the higher occurrence rates of 30-day cardiac shock, heart failure (HF) and life-threatening arrhythmia, P<0.001. With adjusted affecting factors of age, diuretic and reperfusion treatments, serum sodium<130 mmol/L was still related to 7-day and 30-day mortality (OR=1.69 and OR=1.57). Both single and multivariable analysis indicated that serum sodium<130 mmol/L was related to cardiac shock (OR=1.75 and OR=1.64), HF (OR=1.42 and OR=1.30) and life-threatening arrhythmia (OR=1.53 and OR=1.34). In all 3 groups, the patients using ACE inhibitor, β-blocker or both medications had reduced 30-day mortality than those without such medication, allP<0.001; the reduction was more obvious in Serum sodium<130 mmol/L group than the other 2 groups,P<0.001. Conclusion: Serum sodium level<130 mmol/L within 24h of admission was the risk factor for the early stage main adverse events as mortality, cardiac shock, HF and life-threatening arrhythmia in acute STEMI patients.

Objective To investigate the relationship between abnormal metabolism of aggrecan and joint destruction in patients with rheumatoid arthritis (RA).Methods 140 RA patients with duration less than 24 months were enrolled into this study.The study also included 100 normal controls and 95 patients with other rheumatic diseases.Three monoclonal antibodies (5D4,7D4 and BC-3) of aggrecan were used to detected aggrecan catabolic fragments in serum of RA patients and the other two groups of controls by enzyme linked immunosorbent assay (ELISA),and the correlation of aggrecan catabolic fragments with joint damage were analyzed.Sharp evaluation of hand joints in RA patients were performed at baseline and after one year follow-up.Calculating the area under the receiver operating characteristic curve (ROC) was used to evaluate the sensitivity and specificity of aggrecan catabolic fragments detected in serum of RA patients.Results Both levels of 5D4 fragment and BC-3 fragment of RA group were higher than those of normal control [5D4 of RA:(5.8±2.1) ng/μl,normal control:(2.2±1.3) ng/μl;BC-3 of RA:(11.1±3.4) ng/μl,normal control:(5.0±2.1) ng/μl,F=38.65,24.07,P＜0.001).There was no difference in 7D4 fragment among three groups (F=0.589,P=0.478).Both two fragment levels of RA patients with anti-CCP positive were greater than those patients with anti-CCP negative [5D4:(5.6±1.3) ng/μl vs (4.4±1.1) ng/μl,F=21.23,P＜0.01;BC-3:(12.2±3.9) ng/μl vs (9.3±2.8) ng/μ1,F=27.14,P＜0.01].Linear Regression showed that serum fragments detected by 5D4 and BC-3,and anti-CCP positive were risk factors for Sharp deterioration after one year follow-up.The sensitivity and specificity of combined detection of two aggrecan fragments in serum of RA patients for the prediction of joint Sharp were 56.5％ and 84.2％ respectively.Positive predictive value and negative predictive value are 74.3％ and 70.6％.respectively.Application of areas of ROC to identify the best evaluation of Sharp was 0.798.Conclusion There is positive correlation between aggrecan catabolic fragments in serum and joint Sharp evaluation of RA patients.Detection of aggrecan catabolic fragments in RA patients may predict early joint destruction.

Objective To observe the effects of ginkgolides drops on anginal attacks and peripheral blood levels of microRNA-29 a(miR-29a)and intercellular adhesion molecule-1(ICAM-1)in patients with stable angina pectoris.Methods 78 patients with stable angina pectoris patients,who had visited the cardiology department of our hospital during the period of January 2022 to December 2023,were selected.The patients were divided in a Chinese medicine group or a conventional group by using the random number table method,39 in each group.The conventional group received conventional Western medicine treatment,while the Chinese medicine received ginkgo ketone ester drip pills on the basis of conventional Western medicine therapies.Occurrence of angina attack,treadmill electrocardiogram test indexes,blood rheology,6-minute walking distance,TCM symptom scores and changes in peripheral blood miR-29a and ICAM-1 were observed in the two groups.The rate of nitroglycerin discontinuation or reduction and the incidence of adverse reactions were counted.Results Before treatment,there was no statistically significant difference in occurrence of angina attacks between the two groups(P＞0.05).After treatment,the number of attacks per week,weekly glyceryl trinitrate uses,and duration of each attack decreased in both groups,with a greater decline in the Chinese medicine group than in the conventional group(P＜0.05).Before treatment,there was no statistically significant difference in the indicators of treadmill electrocardiogram test between the two groups(P＞0.05).After treatment,induction positive time,exercise termination time,and maximum ST depression time increased in both groups,with longer induction positive time and maximum ST depression time in the Chinese medi-cine group than in the conventional group,while exercise termination time,as compared with the baseline,did not differ statistically(P＞0.05).Maximum ST depression amplitude and ST recovery time decreased in both groups,with a greater decrease in the Chinese medicine group than in the conventional group(P＜0.05).Before treatment,there were no statistically significant differences in miR-29a,ICAM-1,and rheology between the two groups(P＞0.05).After treatment,ICAM-1 and whole blood high/low shear viscosity,FIB,platelet aggregation rate,and plasma viscosity decreased in both groups,with a bigger drop in the Chinese medicine group than in the conventional group(P＜0.05).As compared with the baseline,miR-29a did not differ statistically between the two groups(P＞0.05).Before treatment,there were no statistically significant differences in 6min walking distance and Chinese medicine symptom scores between the two groups.After treatment,6 min walking distance increased in both groups,with a greater increase in the Chinese medicine group than in the conventional group(P＜0.05);Chinese medicine symptom scores decreased in both groups,with a greater decrease in the Chinese medicine group than in the conven-tional group(P＜0.05).The glyceryl trinitrate reduction rate was higher in the Chinese medicine group(79.49%,31/39 cases)than in the conventional group(56.41%,22/39 cases),and the incidence of adverse reactions did not differ statistically between the Chinese medicine group and the conventional group(7.69%vs.5.13%,3/39 vs.2/39 cases;P＞0.05).Conclusions Ginkgolides drops for stable angina improve the degree of myocardial ischaemia and blood rheology,reduce angina attacks,lower ICAM-1 levels,and increase the rate of nitroglycerin discontinua-tion or reduction.

Objective To screen protein disulfide isomerase(PDI)inhibitors from zinc- and selenium-rich green tea and to examine the effect of PDI inhibitors on platelet aggregation. Methods Protein structure file of PDI(PDB ID:4EKZ)was downloaded from protein data bank and the current known 20 compounds in green tea were used to establish a small chemical library. The effects of 6 hit compounds by virtual screening on enzymatic activity of PDI were validated. The antiplatelet activities of the effective compounds tested on PDI enzymatic activi ty were further evaluated. Results 2 of 6 hit compounds by virtual screening ,ECG and EGCG displayed inhibitory effect on enzymatic activity of PDI. In addition ,both compounds showed the potential inhibitory effect on platelet aggregation induced by adenosine diphosphate (ADP) in vitro. Conclusion The effect of blood-activating and stasis-dissolving regulation of green tea is associated with its inhibitory effect on PDI. ECG and EGCG are major active components.

Objective: To explore the interaction of health literacy and second-hand smoke exposure on psychopathological symptoms of middle school students. Methods: From November 2015 to January 2016, 22 628 middle school students from Shenyang of Liaoning Province, Bengbu of Anhui Province, Xinxiang of Henan Province, Ulanqab of Inner Mongolia Autonomous Region, Chongqing Municipality, and Yangjiang of Guangdong Province were enrolled by using the multi-stage cluster convenience sampling method. A questionnaire was used to collect the data including demographic information, health literacy, second-hand smoke exposure, and psychopathological symptoms. A multivariate logistic regression model was used to analyze the interaction of health literacy and second-hand smoke exposure on psychopathological symptoms of middle school students. Results: The age of students was (15.36±1.79) years old, of which 10 990 were boys, accounting for 48.6% of total students. The detection rate of psychopathological symptoms was 29.1% (6 581/22 628). The detection rate of psychopathological symptoms in those who were exposed to second-hand smoke was 38.1% (2 401/6 304), which was higher than that in the non-second-hand smoke exposure group [25.6% (4 180/16 324)] (P<0.001). The OR (95%CI) of the interaction between medium and low levels of overall health literacy, low level of interpersonal dimension of health literacy and second-hand smoke exposure was 1.19 (1.15-1.24), 2.00 (1.92-2.10) and 1.59 (1.52-1.66), respectively. Conclusion There was a positive interaction between middle and low levels of overall health literacy, low level of interpersonal dimension of health literacy and second-hand smoke exposure on psychopathological symptoms of middle school students.

Objective To investigate the effects of Chaihu-Longgu-Muli Decoction (CLMD) on superoxide dismutase (SOD) and maiondiaidehyde (MDA) in patients with temporal lobe epilepsy (TLE).Methods 65 patients with TLE were randomly divided into Oxcarbazepine group (n =32) and Oxcarbazepine + CLMD group (n =33).After 28 d,the curative effect,SOD,MDA changes in serum and side effect were observed between two groups.Results The clinical effective rate in Oxcarbazepine + CLMD group was 87.8％,slightly higher than that of the Oxcarbazepine group(53.1％) (P ＜0.05).After treatment,serum SOD was significantly higher in the patients than before treatment in two groups,but serum MDA was significantly lower(P ＜ 0.05 or P ＜ 0.01),while the above changes were more obvious in the Oxcarbazepine + CLMD group (P ＜ 0.05).No statistically significant differences of side effect (P ＞ 0.05).Conclusions CLMD has higher curative effect with less side effect,which can lead to increase of the level of SOD and decrease of the level of MDA,and the mechanism is related to oxidative stress.
