ABSTRACT

Objective:To investigate the incidence, clinical characteristics and risk factors for hip fractures in patients within two years after stroke onset.Methods:A total of 332 persons with first-onset stroke from the neurology department of our hospital between 1 June 2013 and 31 December 2014 were recruited and were divided into the hip fracture group and the non-hip fracture group.Clinical characteristics were recorded.Vision was tested as normal or impaired.Patients were accessed by the National Institutes of Health Stroke Scale(NIHSS), Behavioral Inattention Test, Baking Tray Task, Mini-Mental State Examination(MMSE), Birgitta Lindmark(BL)motor assessment scale, Berg Balance Scale(BBS), Timed Up & Go(TUG)Scale, and Stops Walking When Talking(SWWT)Scale.The clinic characteristics and risk factors for hip fractures were compared between the two groups after a 2-year follow-up.The accuracy of risk factors for fracture prediction was assessed by the sensitivity, specificity, and positive and negative predictive values.Results:Of 332 patients with stroke, 16 cases fractured their hips within two years after stroke onset, which corresponded to an incidence of 33‰/year(95% CI: 15‰/year-50‰/year). The 2-year mortality rate was 44%(95% CI: 25%-60%)and 48%(95% CI: 42%-54%)in patients with and without hip fractures respectively( χ2=0.036, P=0.724). The mean survival time for patients with and without hip fracture was 2.72 years(95% CI: 1.45-2.79)and 2.21 years(95% CI: 1.48-2.34)respectively.The proportions of patients with previous fractures history( χ2=16.780, P=0.041)and impaired vision( χ2=11.210, P=0.027), MMSE scale score( U=14.220, P=0.031), TUG ≥ 15 s( χ2=18.560, P=0.000)were higher, and SWWT( χ2=20.340, P=0.000)was lower in the hip fracture group than in the non-hip fracture group.The negative predictive values of previous fractures history, impaired vision, TUG and SWWT were higher than their positive predictive value.The specificities of previous fractures history, impaired vision, and SWWT were higher than their sensitivities.And the sensitivity of TUG was higher than its specificity. Conclusions:Hip fractures after stroke are common in elderly patients.Fractures often occur during daytime at home in daily activities.The previous fractures history, visual and cognitive dysfunction and impaired functional mobility are risk factors for hip fractures.We should take measures to prevent falls according to the relevant factors.Among the test scales, the timed up & go(TUG)scale could much more accurately identify patients at high risk for hip fractures.

ABSTRACT

Objective:To explore the association of peripheral blood neutrophil lymphocyte ratio(NLR) with primary osteoporosis (POP) in Chinese elderly women.Methods:From December 2015 to April 2019, a total of 788 elderly women in Chongqing Three Gorges Central Hospital were included in this study.They were divided into three groups according to bone mineral density: 242 cases of osteopenia, 206 cases of normal bone mineral density and 340 cases of osteoporosis.Their height, weight, statuses of bone of left femoral neck and results of blood tests were recorded, and the values of BMI, NLR and OSTA were calculated.The SPSS statistics software was used to analyze the differences of parameters among the three groups.Logistic regression analysis was used to get significant independent related factors for osteoporosis.The relationship of NLR and OSTA with T-score of left femoral neck was confirmed by Pearson correlation test.ROC curves were used to define the values of NLR and OSTA in diagnosis of osteoporosis.Results:There were statistically significant differences in age(median values: 66, 68 and 70, χ 2=71.596, P<0.001), BMI(median values: 23.46, 24.04 and 25.415, χ 2=64.936, P<0.001) and NLR(median values: 1.97, 2.435 and 2.84, χ 2=106.218, P<0.001) among the three groups(all P<0.01). Logistic regression analysis demonstrated that age, BMI and NLR were all independent significant related factors.There was correlation of NLR, OSTA with T-score of left femoral neck.In diagnosis of osteoporosis, the cut-off value, maximum Youden index, sensitivity and specificity were 2.395, 0.299, 70.3%, 59.6% for NLR, and -1.315, 0.174, 73.6%, 43.5% for OSTA. Conclusion:NLR has intermediate sensitivity and specificity in screening POP in Chinese elderly women, and deserves future researches.

Objective To analyze the incidence and epidemic characteristics of Class A and B infectious diseases in Jiading District of Shanghai from 2014 to 2019,understand the prevention and control effects of infectious diseases in recent years,and provide a reference for the formulation of future prevention and control strategies and measures for infectious diseases. Methods According to the " China Disease Prevention and Control Information System",statistical analysis was conducted on the data of Class A and B infectious diseases in Jiading District of Shanghai from 2014 to 2019. Results A total of 11 862 cases of Class A and B infectious diseases were reported in Jiading District of Shanghai from 2014 to 2019,with an average annual incidence rate of 127.34/100000. The overall reported incidence rate showed a downward trend (χ2=36.354,P =0.0002=818.269,P=0.000<0.05) .The high incidence age was 5- years old, followed by 20- years old. The top three occupations in terms of morbidity were workers, housework, unemployed,and retired.In terms of onset time,December and May-June were the two peak periods; February was the trough.Conclusion Class A and B infectious diseases in Jiading District of Shanghai showed a downward trend from 2014to 2019. Blood-borne and sexually transmitted infections and respiratory infectious diseases are still infectious diseases that need to be focused on prevention and control,mainly syphilis,gonorrhea and tuberculosis. Targeted prevention measures should be formulated in conjunction with peak onset times and key populations to further reduce the incidence of Class A and B infectious diseases.

ABSTRACT

Objective To analyze the epidemiological characteristics of syphilis in Jiading District of Shanghai from 2014 to 2018, and to provide a scientific basis for the development of future syphilis prevention and control work. Methods According to the date of onset, all syphilis cases in the infectious disease report information management system from 2014 to 2018, and their epidemic characteristics were analyzed using descriptive epidemiological methods. Results A total of 2 992 cases of syphilis were reported in Jiading District from 2014 to 2018, with an average annual incidence of 38.89/100 000. The overall incidence showed a downward trend year by year. Recessive syphilis was the main cause, and the incidence increased year by year. Fetal syphilis was relatively small and the incidence decreased year by year. The composition ratios of recessive syphilis, primary syphilis, secondary syphilis, and tertiary syphilis in different years were significantly different, and the differences were statistically significant (χ2=26.955, P2=17.793, P=0.0012=12.701, P=0.0130.05). 20~39 years old had the highest incidence rate of syphilis. The areas with high incidence were mainly concentrated in the old urban area of Jiading Center and areas with high population density. The occupational distribution was mainly concentrated in young and middle-aged household workers and unemployed people, workers and elderly retirees. Conclusion In recent years, the syphilis epidemic in Jiading District of Shanghai has shown a downward trend. However, the situation of prevention and control was still severe. It is necessary to continue to improve the level of syphilis detection, and to detect and treat syphilis early. Meanwhile, it is important to strengthen publicity and education in key areas and key populations, and increase awareness of disease prevention to reduce the incidence of syphilis.

ABSTRACT

Objective To evaluate the effect of intelligentized patient-controlled analgesia ( PCA) management on the quality of postoperative analgesia in the patients. Methods A total of 6601 patients who underwent postoperative PCA from January 1, 2015 to December 31, 2017 searched from the intelli-gentized PCA system database were selected as intelligentized PCA management group ( I group) , and then were divided into 3 subgroups according to the year: 2015 subgroup ( n=2221 ) , 2016 subgroup ( n=2152) and 2017 subgroup (n=2228). A total of 1235 patients who underwent PCA which was mainly performed by a department of anesthesiology in the postoperative analgesia-related multi-center questionnaire from April 11, 2016 to April 22, 2016 in 12 grade A tertiary hospitals in Guangdong Province were select-ed as the traditional PCA management group (C group). The development of moderate and severe pain, nausea and vomiting, over-sedation at rest and during activity and patient′s satisfaction were recorded on 1st and 2nd days after operation. Results Compared with C group, the incidence of moderate and severe pain, nausea and vomiting and over-sedation at rest and during activity was significantly decreased, and the rate of patient′s satisfaction was increased at each time point after operation in I group ( P<0. 05 or 0. 01) . Com-pared with 2015 subgroup, the incidence of moderate and severe pain at rest and severe pain during activity was significantly decreased in 2016 and 2017 subgroups ( P<0. 05 or 0. 01) , and the incidence of nausea and vomiting was significantly increased in 2017 subgroup ( P<0. 05) . Compared with 2016 subgroup, the incidence of nausea and vomiting was significantly increased in 2017 subgroup (P<0. 05). Conclusion Intelligentized PCA management can improve the efficacy of PCA, mitigates the occurrence of adverse reac-tions and raise the quality of postoperative analgesia in the patients.

ABSTRACT

Objective To observe the clinical safety and efficacy of foscarnet prophylaxis and pre-emptive therapy for cytomegalovirus (CMV) infection in allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods Ninety-six patients undergoing allo-HSCT from October 2014 to December 2016 were retrospectively analyzed. Plasma CMV-DNA was monitored with real-time quantitative polymerase chain reaction (RQ-PCR) from beginning to 180 days after transplantation. Foscarnet was used not only for prophylaxis but also for first-line pre-emptive therapy when plasma CMV-DNA turned to positive. Foscarnet was given 60 mg·kg-1·d-1 and 120 mg·kg-1·d-1 respectively in prevention and pre-emptive therapy. Incidences of CMV infection and CMV disease were observed, influencing factors on CMV in faction and the efficacy and safety of foscarnet prophylaxis were analyzed, and survival of patients treated by all-HSCT was evaluated. Results Of the total 96 patients, 42 cases (43.8%) had CMV infection with the median time of 42 days after allo-HSCT. CMV-DNA became negative in 36 patients (85.7%, 36/42) after pre-emptive therapy. Six patients (14.3 %, 6/42) developed CMV disease, including 5 patients with CMV negative and 1 patient died for CMV pneumonia. Haploidentical donor and grade Ⅱ-Ⅳacute graft versus host disease (GVHD) were the risk factors for CMV reactivation (χ2 = 3.834, P< 0.05; χ2 = 16.807, P< 0.001). The side effects of foscarnet prophylaxis were mild without hematologic toxicities. 12 patients (28.6 %) died in 42 patients with CMV infection, and 6 patients (11.1 %) died in 54 patients without CMV infection. The difference of survival rates between both groups was not statistically significant. Conclusion Foscarnet is an effective agent for prophylaxis and pre-emptive therapy in CMV infection after allo-HSCT with mild adverse reactions, especially for patients following with hematopoietic recovering.

ABSTRACT

Objective To explore the expression of aquaporin 4 (AQP4) in primary and secondary cultured rat astrocytes. Methods Rat cortical astrocytes from a newborn (one day) Wistar rat were cultured. Astrocytes were identified with immunofluorescence staining of glial fibrilillary acidic protein (GFAP). The expression of AQP4 was determined with real-time quantitative polymerase chain reaction and immu-nofluorescence staining three, five, seven and nine days of primary culture, and nine days of secondary culture. Results The purity of GFAP-positive cells was more than 95%. The expression of AQP4 mRNA was found three days of primary culture, remained unchanged five days of primary culture (P>0.05), and increased seven and nine days of primary culture (P0.05). AQP4 immunofluorescence staining showed the same trend of AQP4 mRNA. Conclusion AQP4 may express since three days of primary culture in rat astrocytes in vitro, and increase slowly until nine days of primary culture.

ABSTRACT

Objective To investigate the expression changes of astrocytic syntrophin in hippocampus from human mesial temporal lobe epilepsy (MTLE). Methods From April, 2015 to July, 2016, 17 cases of hippocampus, collected from temporal lobectomy, were divided into MTLE group (n=13) and non-MTLE group (n=4) according to hematoxylin and eosin staining, glial fibrillary acidic protein and neuronal nu-clei immunohistochemical staining. Immunofluorescence double labeling and immunofluorescence histochemistry were used to observe the expression of syntrophin. Results The proliferation of astrocytes increased and neurons reduced in the hippocampus of MTLE group. Syntro-phin was found in the membrane and foot processes of astrocyte, that was enriched along perivascular astrocyte end-feet domain in non-MTLE group, but lost in MTLE group. While the whole expression of syntrophin was more in MTLE group than in non-MTLE group (t=5.421, P<0.001). Conclusion The distribution of syntrophin in hippocampus astrocytes may be related to the development of MTLE.

ABSTRACT

Objective To compare the differences between the cell swelling of cultured astrocytes ( AST) from Wistar and Sprague-Dawley ( SD) rats after incubation with glutamate.Methods Primary cultured AST derived from the cerebral cortex of one-day-old Wistar or SD rats were prepared.The cultured AST received 1 or 10 mmol/L glutamate treat-ment for 48 h on the tenth day after subculture.The viability of AST was determined by lactate dehydrogenase ( LDH) kit to assess the cell injury, and the perimeter of AST was measured using Image Pro Plus software after glial fibrillary acidic protein immunofluorescence staining to evaluate the astrocyte swelling.Then, the expression of aquaporin 4 ( AQP4 ) in cultured AST was detected by quantitative reverse transcription polymerase chain reaction.Results No significant differ-ence was found in the LDH release after the glutamate treatment in cultured AST from these two strains (P>0.05).The perimeter of AST from normal Wistar rats was shorter than that from SD rats, but was longer after the treatment of glutamate (P<0.05).Meanwhile, AQP4 expression in the Wistar rats was significantly higher than that from SD rats after incuba-tion with 1 mmol/L glutamate ( P<0.05 ) .Conclusions These results suggeste that cultured AST from Wistar rats are more susceptible to glutamate-induced swelling than that from SD rats, and there are differences between the effects of glu-tamate on AQP4 expression in astrocytes of Wistar and SD rats.

ABSTRACT

Objective To investigate the protective effect of methylene blue (MB) on blood-brain barrier (BBB) injury after focal cere-bral ischemia-reperfusion in rats. Methods 18 male Sprague-Dawley rats were randomly divided into sham-operated group (n=6), model group (n=6) and MB treatment group (n=6). The left middle cerebral arteries were occluded for 1 hour and reperfused. MB was infused intra-venously immediately after reperfusion (3 mg/kg) and again 2 hours post-reperfusion (1.5 mg/kg), while normal saline was administered in the model group. The sham-operated group was treated as same as the model group without occlusion and infusion. HE staining was used to observe the histological injury in the cortex around the infarcted region 47 hours after reperfusion, while albumin immunohistochemistry was used to evaluate the permeability of the BBB, and immunohistochemistry and double immunofluorescence staining were used to exam-ine the expressions of glial fibrillary acidic protein (GFAP) and aquaporin-4 (AQP-4). Results HE staining showed that cells and blood ves-sels were not intact in the cortex around the infarcted region in the model group and they were better in the MB treatment group. The expres-sions of the albumin, GFAP and AQP-4 were higher in the model group than in the sham-operated group (P<0.01), and were lower in MB treatment group than in the model group (P<0.05). The double immunofluorescence staining showed the colocalization of GFAP and AQP-4 in the astrocytes. Conclusion MB may ameliorate the BBB disruption induced by focal cerebral ischemia-reperfusion through reducing glio-cyte proliferation and down-regulation of AQP-4 expression in rats.

ABSTRACT

Objective To evaluate the different effects of laryngeal mask and mask ventilation during bronchoscopy in elder patients. Methods 120 old patients (ASA I-III) were divided into three group according to the table of random number as following:surface anesthesia with autonomous respiration (group I);endoscope mask ventilation (group II);laryngeal mask airway ventilation (group III). Oxygen inhalation through nasal tube in groupⅠ,group II and group III was ventilated with endoscope mask and LMA respectively ,thenwe observed whether there were adverse effects or not during the procedure. Results The adverse reactions of group I were more than other groups. Compared with the group I, variance of MAP,HR, RR, SpO2 in the groupⅡand groupⅢ had less changes, the cases with severe bucking decreased significantly, and satisfaction degree increased markedly, (P <0.01or P<0.05 ) . The incidence rate of resp iratory depression and airway obstruction in groupⅡwas higher than that in groupⅢ (P<0.05). Conclusion Endoscope mask ventilation and LMA can both be adopted in analgesia bronchoscopy for old patient. LMA under general anesthesia to transbronchial lung biopsy would control respiration according to the demand at any time.LMA has more advantage in the operation for the stable respiration and hemodynamics and less complications.

ABSTRACT

Objective To evaluate the effect of remote limb ischemic postconditioning on the level of adiponectin during myocardial ischemia-reperfusion (I/R) in rats.Methods Fifty-seven male Sprague-Dawley rats,aged 8 weeks,weighing 250-350 g,were randomly divided into 3 groups (n =19 each):sham operation group (group S); group I/R; remote limb ischemic postconditioning group (group RLIP).Myocardial ischemia was induced by occlusion of anterior descending branch of left coronary artery for 30 min followed by 180 min reperfusion in urethane-anesthetized rats.In group S,the anterior descending branch was only exposed but not ligated.The animals underwent 10 min ischemia of bilateral hind limbs starting from 20 min of occlusion of the anterior descending branch,followed by reperfusion in RLIP group.The changes in S-T segment were recorded at 30,60,120 and 180 min of reperfusion.At 180 min of reperfusion,the blood samples were taken from the jugular vein for determination of serum levels of creatine kinase MB (CK-MB) and cardiac troponin Ⅰ (cTnⅠ).The animals were then sacrificed and hearts were removed for measurement of myocardial infarct size (IS) and adiponectin contents in myocardial tissues (by ELISA).Results Compared with group S,S-T segment was significantly elevated at each time point,myocardial IS,and serum cTnⅠ and CK-MB levels were increased,and adiponectin contents were decreased in I/R and RLIP groups.Compared with group I/R,elevation of S-T segment was significantly decreased at each time point,myocardial IS,and serum cTnⅠ and CK-MB levels were decreased,and adiponectin contents were increased in RLIP group.Conclusion The mechanism by which remote limb ischemic postconditioning reduces myocardial I/R injury is related to increased level of adiponectin in the myocardium of rats.

ObjectiveTo investigate the influence of age on hypnotic target plasma concentration (CT) of dexmedetomidine (Dex) administered by TCI.MethodsSixty ASA Ⅰ - Ⅱ patients aged 18-85 yr undergoing lower abdominal or extremity operation under combined spinal-epidural anesthesia were divided into 2 age groups ( n =30each):18 yr<groupⅠ<55 yr (Y) and 65 yr<group Ⅱ<85 yr (E).Each group was further divided into 5subgroups (n =6 each) receiving Dex administered by TCI at CT of 0.54,0.64,0.76,0.90,1.07 ng/ml in group Y and 0.36,0.42,0.51,0.60,0.71 ng/ml in group E respectively.Hypnosis was defined as no response to verbal command (OAA/S score ≤2) and loss of eyelash reflex.A quantal response model (probit analysis) was used to calculate the concentration-effect curve and predict plasma EC50 and EC95 (95%CI) of Dex.ResultsEC50 (95%CI) was 0.478(0.424-0.536) ng/ml and EC95(95%CI) 0.641 (0.567-0.816) ng/ml in group E,significantly lower than EC50 (95 % CI) 0.738 (0.657-0.827) ng/ml and EC95 (95%CI) 0.990 (0.874-1.267 ) ng/ml in group Y.ConclusionThe EC50 and EC95 of dexmedetomidine for hypnosis were significantly lower in the elderly than in younger patients.

ABSTRACT

The complete coding sequence of Haemonchus (H.) contortus HC29 cDNA was generated by rapid amplification of cDNA ends in combination with PCR using primers targeting the 5'- and 3'-ends of the partial mRNA sequence. The cloned HC29 cDNA was shown to be 1,113 bp in size with an open reading frame of 507 bp, encoding a protein of 168 amino acid with a calculated molecular mass of 18.9 kDa. Amino acid sequence analysis revealed that the cloned HC29 cDNA contained the conserved catalytic triad and dimer interface of selenium-independent glutathione peroxidase (GPX). Alignment of the predicted amino acid sequences demonstrated that the protein shared 44.7~80.4% similarity with GPX homologues in the thioredoxin-like family. Phylogenetic analysis revealed close evolutionary proximity of the GPX sequence to the counterpart sequences. These results suggest that HC29 cDNA is a GPX, a member of the thioredoxin-like family. Alignment of the nucleic acid and amino acid sequences of HC29 with those of the reported selenium-independent GPX of H. contortus showed that HC29 contained different types of spliced leader sequences as well as dimer interface sites, although the active sites of both were identical. Enzymatic analysis of recombinant prokaryotic HC29 protein showed activity for the hydrolysis of H2O2. These findings indicate that HC29 is a selenium-independent GPX of H. contortus.
