We investigated health condition and evaluate the viability of Barthel's measuring scale for 1297 elder patients at 17 nursing homes.We nursed all patients by standards and performed a comparison study.The nursing percentages of highest and lowest levels were higher than the previous ones ( P ＜ 0.01 ),while the nursing percentage of normal level was lower than the previous one ( P ＜ 0.01 ).The cooperation between doctors and nurses became optimized through progressive patient care.Ideal nursing standard should be based upon the doctors' judgment and nurses' evaluation.The new standard will be more suitable for patients and easier to control for nurses.

Objective To investigate the effects of suramin application in acute angle closure glaucoma surgery patients.Methods A prospective study method was used.From February 2012 to January 2016,178 acute angle closure glaucoma surgeries in our hospital for treatment were selected,and were equally divided into observation and control groups (89 cases in each group) according to the order of admission,and two groups were given filtration surgery.The observation group was treated with suramin adjuvant therapy after surgery.The duration were 1 ～ 14 d after operation.The prognosis of two groups was observed.Results All patients were successfully completed surgery.The intraoperative and postoperative complications were no seriously occurred;the postoperative intraocular pressure in the observation group and the control group were (11.52 ± 3.24) mmHg and (16.98 ± 5.33) mmHg that compared preoperative [(31.98 ± 5.22) mmHg,(31.87 ± 5.11) mmHg] with significantly different (P ＜ 0.05),while the observation group was significantly lower than that of the control group (P ＜ 0.05).The postoperative peak systolic velocity (PSV) and end diastolic velocity (EDV) values of the central retinal artery of the observation group and the control group were significantly higher than that of preoperation (P ＜ 0.05),and the postoperative PSV and EDV values of the central retinal artery of the observation group were significantly higher than that in the control group (P ＜ 0.05).The postoperative ratios of functional filtering bleb in the observation group and control group were 80.9％ and 60.7％,respectively.The observation group was significantly higher than that of the control group (P ＜ 0.05).Conclusions The application of suramin in acute close angle glaucoma filtration surgery can promote the function of filtering bleb and intraocular pressure reduction,and improve the ocular blood flow speed that has good application effects.

OBJECTIVE:To provide reference for improving the cognition of medical staff for adverse drug reactions(ADR). METHODS:A questionnaire survey was conducted on the spot among the physicians,nurses and pharmacists with different profes-sional titles in our hospital to investigate their cognition about ADR concept,their judgment for ADR and ADR reporting,and the results were analyzed by statistical methods. RESULTS:Totally 452 questionnaires were sent out,and 439 were effectively re-ceived,with effective rate of 97.12%. In terms of correct cognition rate about ADR basic concept and the main reasons,the sur-veyed pharmacists were higher than physicians and nurses,the senior professional titles of surveyed pharmacists were higher than the intermediate and junior,the pharmacists with senior professional titles were the highest and the junior were the lowest,the dif-ferences were statistically significant(P<0.05);in terms of the proportion of certain for ADR judgment,the surveyed nurses were lower than pharmacists and physicians,the surveyed physicians with senior and intermediate professional titles were higher the ju-nior,the surveyed nurses with intermediate titles were higher than the junior,the surveyed pharmacists with senior professional ti-tles were higher than the intermediate and the junior,the differences were statistically significant(P<0.05);in terms of cognition about ADR reporting,the surveyed pharmacists were the highest and the nurses were the lowest,the differences were statistically significant (P<0.05),while in terms of the proportion of knowing ADR reporting timing limit,reporting procedures and depart-ments,the surveyed pharmacists and physicians with junior professional titles were lower than the senior and intermediate,the dif-ferences were statistically significant(P<0.05);in terms of reasons for missed ADR reporting,the proportion of consideration of the risk of causing medical disputes for doctors of the surveyed physicians was higher than pharmacists and nurses,while the sur-veyed nurses showed higher proportion for doing not understand reporting procedures,doing not reporting,thinking ADR reporting was dispensable and uncertain for ADR identification,the differences were statistically significant (P<0.05). CONCLUSIONS:Medical staff with different professional titles and occupations have different cognition about ADR basic concept,judgment and re-porting,the pharmacist are relatively good,followed by the physician and nurse,especially the nurse,and the medical staff with junior professional titles are relatively poor. It is necessary to strengthen ADR education and training for them,play professional ad-vantages from the pharmacist and optimize ADR reporting procedures to improve the reporting rate and quality of ADR.

Objective To evaluate the effect of CT temporal subtraction(TS) for detection of lung nodules.Methods 80 cases of CT images (current and previous CT images) and corresponding CT TS images were presented, which included 30 cases with nodules(75 nodules) and 50 controls.4 observers, including 2 radiologists and 2 residents, indicated their confidence level regarding the presence of a new emerging or larger or solid component than before,which first used standard CT images, then with the addition of CT TS images.Receiver operating characteristic(ROC) curve analysis was used to evaluate the observers'' performance.Results The mean value of the area under the ROC curve (AUC) were 0.860 and 0.925 for four observers without and with TS images,respectively(P<0.01).Average sensitivity for detection of lung nodules was improved from 77.3%(58/75) to 89.3%(67/75) by using CT TS images.Conclusion The use of CT TS images can significantly improve radiologists'' performance for detection of lung nodules,especially when a small size solid or subsolid nodule presents near the pulmonary hilum.CT TS is more helpful for residents.

Objective To evaluate the performance of bone suppression images on the detection of lung nodules in comparison with the radiologists'reading results.Methods There were 141 standard posteroanterior digital chest radiographs,which included 95 patients with a solitary nodule and 46 controls.In this observational study,4 observers,including 2 radiologists and 2 residents,in-dicated their confidence level regarding the presence of a nodule for each lung,first by use of standard images,then with the addition of bone suppression images.Receiver operating characteristic (ROC)curve analysis was used to evaluate the observers'performance. Results Average nodule size was (1.9±1)cm (range from 0.9 cm to 2.9 cm).The mean value of the area under the ROC curve (AUC)was significantly improved from 0.844 with use of standard images alone to 0.873 with use of bone suppression images (P<0.01).Conclusion The use of bone suppression images can improve radiologists'performance on detection of lung nodules on chest radiographs.

OBJECTIVE To define the regularity of survival ability of HIV in natural environment,and prevent(infection) through contacting with positive body fluids during daily life or medical work.METHODS Having been diluted by sterile water or 10% serum RPMI 1640 medium,HIV was exposed to 4℃,room temperature(20-26℃) or 37℃ for different period of time.TCID_(50) of these samples was detected.Non-pathological samples were blind passaged for three generations.RESULTS HIV infective ability persisted more than 35 days both in(water) and medium at 4℃;whereas it persisted 7-14 days in water,14-21 days in medium at room temperature and 37℃.CONCLUSIONS HIV has higher resistance in natural environment.To prevent accidental spreading of HIV,HIV positive liquids and contaminants staffs should be treated carefully.

OBJECTIVETo observe the changes of behavior and amino acids in brain tissue of rats with adjuvant arthritis, and effects of Xinfeng Capsule (XFC) on them.

METHODSAA model was induced by complete Freund's adjuvant in rats. Five groups including the normal control group, the model group, the XFC group, the methotrexate (MTX) group and the Tripterygium wilfordii polysaccharide (TPT) group were set up. The changes of behavior, amino acids in brain tissue, swelling degree of joints, and arthritis index (AI) were observed and the correlation analysis on these indexes was performed.

RESULTSCompared with those in the normal control, the frequency of independent activity obviously decreased in the model rats, accompanied with increased number of step-down errors, shortened step down latency (SDL) and prolonged escape latency (EL), also the level of gamma-aminobutyric acid (GABA) in brain tissue elevated and glutamic acid (GLU)/GABA reduced (P <0.05). Compared with those in the model group, all the above indexes were improved significantly in the XFC group after treatment (P <0.05), while they changed insignificantly in the MTX and TPT groups (P> 0.05), the degree of joint swelling and AI were obviously lower in the 3 treated groups (P< 0.05). Correlation analysis showed the frequency of independent activity and SDL were negatively correlated to the swelling degree of joint, and levels of AI, glycine (GLY) and GABA respectively, but positively correlated with GLU/GABA (P<0.05); while EL and number of step-down errors were positively correlated to AI, GLY and GABA respectively, but negatively correlated to GLU/GABA (P < 0.05).

CONCLUSIONImmune stress could lead to the changes of rat behavior and amino acids in brain tissue. XFC treatment could improve the behavior of AA rats through regulating the levels of amino acids in brain tissue.

Objective To investigate the potential clinical factors associated with the prognosis and relapse of adult onset Still's disease(AOSD).Methods The factors possibly influencing the prognosis and relapse of AOSD were analyzed by logistic regression and COX regression in the cohort study.Ninety-six con- secutive inpatients of AOSD diagnosed based on Yamaguchi criteria in the hospital from March 1996 to September 2004 were included in the study.Results Nine cases(9.4%)were lost during the follow-up. Eleven patients(12.6%)were diagnosed as other diseases(5 with other rheumatic diseases,4 with tumor and 2 with infections)in the 87 follow-up cases.In 76 cases,3 patients(3.9%)died and 33 patients(43.4%) got remission over one year after treatment.Splenomegaly(OR=3.14,95%CI=1.01～9.74)and treated with methotrexate(OR=0.22,95%CI=0.07～0.67)were associated with the prognosis from the logistic regression analysis of the 76 cases.The serum ferritin(RR=I.05,95%CI=1.01～1.08)and treated with methotrexate (RR=0.13,95%CI=0.02～0.76)were associated with relapse from the COX regression analysis of the 61 remis- sion cases.Conclusion We need to be very cautious in the follow-up of AOSD patients because some of them may change to other diseases.Methotrexate may be an importent therapy of AOSD not only in improve- ment the prognosis but also in reduction of relapse.

Objective To investigate the iodine nutrition level of vulnerable people in Inner Mongolia after adjustment of iodized salt standard and to provide theoretical bases for scientific iodine supplementation. Methods In 2013, 3 cities were selected from eastern, central and western parts of Inner Mongolia in accordance with the random number table, 3 or 4 counties were selected from each target city, 5 units according to their sub-area position of east, south, west, north and center were selected from each county, and then 1 township was selected from each unit, 5 groups of target population including school children aged 8- 10, women of childbearing age, pregnant and lactating women and infants each at least 10 people were investigated in each township. Edible salt samples from their homes and urine samples were collected. The direct titration method among the generic methods of iodide testing for salt production industry (GB/T 13025.7-2012) was used to determine the salt iodine level, and As3+-Ce4+catalytic spectrophotometry using ammonium per sulfate digestion (WS/T 107-2009) was used to test the urinary iodine level. Results Totally 3 300 samples of edible salt from local residents had been examined and median iodine was 26.20 mg/kg. The median of urinary iodine was 190.6μg/L of 1 289 school-age children;was 183.6μg/L of 621 women of childbearing age; was 178.2 μg/L o f 876 pregnant women; was 178.6 μg/L of 664 lactating women and was 167.7μg/L of 599 infants. Conclusion After adjustment of iodized salt standard, iodine nutrition level is suitable in all vulnerable people.

ABSTRACT:OBJECTIVE To investigate the role of connexin proteins (Cx), which form gap junctions (GJ), in progression and chemotherapeutic sensitivity of cervical cancer (CaCx). METHODS We analyze the expression of Cx26, Cx30, Cx32 and Cx43 in human specimens consisting of: Normal cervix (n=78), CaCx FIGO stage Ⅰ (n=148), CaCx FIGO stage Ⅱ (n=165). InCaCx cell lines, Hela- Cx32 (induced expression by doxycycline), C- 33A (endogenously express Cx32) and siHa (transiently transfected plasmid with Cx32), we detected the role of Cx32 against tostreptonigrin/cisplatin-induced apopotosisin presence or absence of functional GJ through using GJ inhibitors or low density cultural.Furtherly, we observed the relativity of Cx32 and EGFR expression in human specimens. Also, we detected the role of EGFR signaling pathway in the process of Cx32 anti-apoptosis through suppressed EGFR expression by inhibitors or siRNA sequences in cell lines. RESULTS We firstly demonstrated the expression of Cx32 was highly upregulated and accumulated in cytoplasm in the CaCx specimens, and the degree of upregulation correlated with advanced FIGO stages. Thus,in three human cervical cell lines, Cx32 was shown to suppress apoptosis when GJ formation is inhibited. No matter in cases of CaCx or cell lines, Cx32 expression was highly correlated with expression of EGFR and the EGFR pathway is an essential component of the Cx32-induced anti-apoptotic effect. CONCLUSION Cx32, traditionally tumor suppressive protein, was shown to be tumor protective against chemotherapy through EGFR pathway in a GJ-independent way.
