To evaluate the charasteristics and risk factors of hospital infections in patients with contagious diseases, 489 patients with contagious diseases were analyzed. Among 18 patients who contracted hospital infections, 17 were suffering from chronic hepatitis. 77 78% of them were over 40 years old. Infection of ascitic fluid, lower respiratory tract, and blood stream comprised 77 78% of the infections. Most of the doctors used antibiotics empirically. The survey showed that patients over 40 years old in an infectious diseases hospital were vulnerable to hospital infections. Hospital infection often occurred in the abdomen, lower respiratory tract, and blood stream. Abdominal paracentesis liver puncture biopsy, and lumbar puncture were the first three exogenous risk factors.

OBJECTIVETo purify the arsenic-binding proteins (As-BP) in hamster plasma after a single oral administration of arsenite (iAs(III)).

METHODSArsenite was given to hamsters in a single dose. Three types of HPLC columns, size exclusion, gel filtration and anion exchange columns, combined with an inductively coupled argon plasma mass spectrometer (ICP MS) were used to purify the As-BP in hamster plasma. SDS-PAGE was used to confirm the arsenic-binding proteins at each purification step.

RESULTSThe three-step purification process successfully separated As-BP from other proteins (ie, arsenic unbound proteins) in hamster plasma. The molecular mass of purified As-BP in plasma was approximately 40-50 kD on SDS-PAGE.

CONCLUSIONThe three-step purification method is a simple and fast approach to purify the As-BP in plasma samples.

BACKGROUND: The treatment of upper cervical spine disorders through a posterior pedicle fixation approach have been carried out in some domestic large hospitals, but this surgery is still considered as a difficulty of cervical spine surgery. In order to minimize the risk of surgery, the authors designed a program of individual operations, and combined with self-developed pedicle locating and directing speculum to determine precise intraoperative position of pedicle screws, and no report is found by searching related database in China.OBJECTIVE: To improve the one-time success rate of internal fixation screws, to investigate the biomechanical effect of the implant, to formulate a simple, practical, individual protocol for atiantoaxial pedicle screw-plate system based on related data. METHODS: A total of 31 patients were recruited from Department of Orthopaedics in the 251 Hospital of Chinese PLA, between January 2002 and September 2006. Under the guidance of self-made atlantoaxial locating and directing speculum, the entrance point and angle for screw insertion, as well as screw diameter and length were determined according to the results of X-ray and CT measurement. Atlas pedicle screw was inserted at left (19.93±1.32) mm, and right (19.16±1.3) mm; Atlas pedicle screw insertion angle to inside was left (23.72±2.09)°, and right (23.35±1.91)°; Atlas pedicle screw insertion angle to side of head was (9.00±1.20)°. Axis pedicle screw was inserted at left (13.14±0.82) mm, and right (13.85±0.79) mm; Axis pedicle screw insertion angle to inside was left (24.52±1.26)°, and right (20.42±1.42)°; Axis pedicle screw insertion angle to side of head was (25.00±3.00)°.RESULTS AND CONCLUSION: ①Totally 124 pedicle screws were implanted into 31 patients, and 122 screws were of one-time success. The precision rate was 98.39%. Two screws were secondly inserted because of cutting lateral cortical bone of pedicle for deviation of inward angle. ②Occipital neuralgia was found in 2 cases postoperatively and cured after one month of treatment;screws penetrated atlas left vertebral lateral wall in 2 cases, no spinal or vertebral artery injury was found. ③Radiographs showed that atlas was completely reduced in all patients, and apposition of dentoid process of axis fracture was good. CT films showed the screws a good location to the vertebrarterial spinal cord. ④The follow-up visit was averaged of 10.5 months. Bony fusion was found in all patients. No screw-plate breakage was found. No inflammatory or rejection reactions occurred.⑤By JOA scale, there were 16 cases of excellent, 12 cases of good, 2 cases of fine, and 1 case of poor. The excellent and good rate was 90%. It is suggested that the success rate of atlantoaxial pedicle screw-plate mplantation can be improved through a biomechanical angle.

Objective To investigate the relationship between serum secreted frizzled-related protein 4 (SFRP4) and the first-phase of glucose-stimulated insulin secretion from pancreatic β cell under different glucose tolerance statuses. Methods Fifty-six patients with newly diagnosed type 2 diabetes mellitus ( T2DM group), 52 patients with impaired glucose tolerance (IGT group), and 42 subjects with normal glucose tolerance (NGT group) underwent intravenous glucose tolerance test. Fasting serum SFRP4 and interleukin ( IL)-1β were assayed by ELISA. Acute insulin response ( AIR), the area under the curve of the first-phase (0-10 min) insulin secretion (AUC), glucose disposition index(GDI), homeostasis model assessment for β cell function index(HOMA-β), and insulin resistance index(HOMA-IR) were calculated. Results (1) The levels of SFRP4 and IL-1β in T2DM group and IGT group were significantly higher than that in NGT group [(184. 38 ± 61. 34 or 141. 64 ± 40. 46 or 95. 46 ± 20. 13)ng/ ml, P<0. 01]. AIR, AUC, and GDI in T2DM group and IGT group were significantly lower than those in NGT group(P<0. 01), and these results were more significantly reduced in T2DM group compared with those in IGT group. (2) SFRP4 was negatively correlated with AIR, AUC, GDI, HOMA-β (P<0. 01), and positively correlated with fasting plasma glucose, 2 h plasma glucose after glucose loading, HbA1C , IL-1β, and high sensitive C-reactive protein(P<0. 01). (3) Multiple stepwise regression analysis showed that AUC, HOMA-IR, and serum IL-1β level were independently associated with SFRP4. Conclusion The concentration of serum SFRP4 is closely correlated with the glycolipid metabolic disorder, the first-phase of glucose-stimulated insulin secretion, and chronic low-grade inflammation. SFRP4 may be involved in the mechanism of β cell dysfunction in type 2 diabetes mellitus.

It is of great clinical significance to improve the diagnosis of HCC.

In our previous work, we found that trivalent dimethylarsinous acid (DMA(III)) have high affinity binding to cysteine residue 13 of rat hemoglobin. However, it is still unknown why arsenic intermediate metabolite DMA(III) has high binding affinity for Cysl3 but not for other cysteine residues 93, 140, 111 and 125. In order to better understand the molecular mechanism of DMA(III) with rat hemoglobin, we have done current study. So, SD rats were divided into control and arsenic-treated groups randomly. Arsenic species in lysate of red blood cells were analyzed by HPLC-ICP-MS, and then determined by a hybrid quadrupole TOF MS. In addition, trivalent DMA(III) binds to different cysteine residues in rat hemoglobin alpha and beta chains were also simulated by Molecular Docking. Only Cys13 in alpha chain is able to bind to DMA(III) from the experiment results. Cys13 of alpha chain in rat hemoglobin is a specific binding site for DMA(III), and we found that amino acids compose pockets structure and surround Cys13 (but not other cysteine residues), make DMA(III) much easy to bind cysteine 13. Taken together, the DMA(III) specific binding to Cys13 is related to spatial structure of Cys13.

Objective To describe the clinical characteristics of idiopathic ventricular fibrillation (IVF) with fragmented QRS complex (f-QRS) and J wave in resting electrocardiogram. Methods We reviewed data from 21 case subjects in our hospital who were resuscitated after cardiac arrest due to IVF and assessed the prevalence of f-QRS and J wave in resting electrocardiogram (ECG). All the case subjects were classified among three groups based on the electrocardiographic morphology: group I, both f-QRS and J wave were observed (n = 6), group II, only J wave was observed (n = 9), group III, neither f-QRS nor J wave was observed (n = 6). Population characteristics, history of syncope or sudden cardiac arrest, incidence of ventricular fibrillation (VF), and circumstance of VF were evaluated among the three groups. Results The incidence of index events (syncope, survived cardiac arrest and VF episodes recorded in implantable cardioverter defibrillator (ICD) or pacemakers) was 13.4 ± 5.6 per-year in group I, 10.8 ± 3.9 per-year in group II, and 9.8 ± 4.2 per-year in group III. There were significant differences in incidences among the three groups, the most frequent index events were observed in group I. The hazard ratio for incidence was 3.2 (95%CI, 1.1-7.9; P = 0.01). The history and circumstance of the index events were different among the groups. In group I, all the index events occurred during sleep in early morning. In group II, four subjects suffered VF during strenuous physical activities or agitation state, two during sleep in early morning, three in usual activity. In group III, one subject suffered VF during sleep in early morning, one in agitation state, four in usual activity. Conclusions This study suggests that the IVF patients with the combined appearance of f-QRS and J wave in the resting ECG suffer an increased risk of VF, this subgroup of IVF patients has a unique clinical feature.

Objective: To investigate the sleep quality of prison policemen and explore its influencing factors, so as to provide reference for improving the sleep quality of prison policemen. Methods: In August 2013, 177 policemen in a prison were selected by cluster sampling. The sleep quality of 177 prison policemen was investigated by Pittsburgh Sleep Quality Index Scale and General Situation Questionnaire, and the influencing factors were analyzed. Results: The PSQI scores of 177 prison policemen were (7.47+3.80). There were significant differences between the PSQI scores of prison policemen and the normal adult norm (P<0.05). According to the standard of poor sleep quality, 84 prison policemen (47.46%) had poor sleep quality, and the prison policemen scored higher on daytime dysfunction, subjective sleep quality, sleeping time and sleeping time components. Single factor t test and single factor variance analysis showed that there were significant differences in sleep quality among prison policemen in gender, age, educational level and job classification (P <0.05). The results of multiple stepwise regression analysis showed that gender, age and job classification entered the regression equation with PSQI total score as dependent variable (β=0.167, 0.270, 0.222) . Conclusion The sleep quality of prison policemen is worse than that of normal adults, and is affected by gender, age, job classification and other factors, which should be paid attention to by prison administrators.

Objective To explore the effect of medication adherence therapy on the survival status of patients with primary depression.Methods From July 2011 to December 2013, 55 cases of depression patients in our hospital were treated as control group, and routine health education was implemented. From January 2014 to June 2016 in our hospital and the 57 first treatment of depression patients choosing for observation group, received the routine care and the implementation of medication adherence for the treatment method of education. The scores were assessed in SDS score at 3 months and 6 months after admission, the quality of life score at admission and 6 months after intervention, and the compliance of treatment at 6 months after the intervention. Results At the time of admission of two groups patients with depression score difference was not statistically significant (t=1.124,P=0.059); after interventions for 3 months and 6 months in the observation group, the patients with depression scores were significantly lower than that of the control group, and the difference was statistically significant (t=3.986, 8.532;P<0.01). The implementation of drug compliance therapy intervention, observation group of patients in the medication compliance, timely review, reasonable rest, reasonable diet, reasonable exercise, prevention of infection, smoking and drinking in 7 dimensions and total score were significantly higher than those of the control group,and there was significant difference between two groups (t= 6.022, 6.954, 5.863, 5.042, 6.514,5.652, 4.675, 5.868;P<0.01). Patients in the observation group in physiological function, psychological function, social function, health self cognition and total quality of life scores improved significantly higher than that in the control group, and the differences were statistically significant (t=5.265, 4.638, 4.267, 4.146, 3.955;P<0.01).Conclusions Medication adherence therapy can improve the treatment compliance of patients, reduce the degree of depression, and improve the quality of life of patients.

Objective To study the influences of group social skills training on marriage quality of married patients with bipolar disorder. Methods A total of 100 patients with bipolar disorder were selected who hospitalized from February 2012 to February 2015, and they were divided into control group and observation group randomly, each with 50 cases. The patients of control group were given routine nursing care, while the patients of observation group were given group social skills training on the basis of routine nursing. Quality of life, family function satisfaction and marital quality were compared between two groups. Results In the observation group, the scores of the patients in the fields of psychology, physiology, environment, and social relationship were higher than that in the control group. Score of family function satisfaction was significantly higher than that of the control group (P <0. 05). In the observation group, the patients′ scores of marital satisfaction (35. 79 ± 6. 73), sexual life (34. 52 ± 6. 48) and husband-wife communication (37. 22 ± 6. 26) were higher than those in control group (P<0. 05). Conclusions Group social skills training in married people with bipolar disorder can improve their quality of life, satisfaction of family function and marital quality.
