Objective To explore the predictive value of cholinesterase (ChE) in the prognosis of gerontal patients with systemic inflammatory response syndrome. Methods The clinical data of 124 elderly patients with systemic inflammatory response syndrome collected from September 2009 through September 2010 were retrospectively analyzed. All patients were divided into death group and survival group according to the outcome of patients. The cholinesterase ( ChE), albumin, D-Dime, lactic acid and C-reactive protein (CRP) were detected, and the APACHE Ⅱ and GCS scores were documented in the first 24 hours in the ICU. Results There were no significant differences in age, gender, APACHE Ⅱ score and GCS score of patients between death group and survival group ( all P ＞ 0. 05 ), but there were significant differences in lactic acid, D-Dime, albumin, CRP and ChE between two groups ( theP values were 0.011,0.011, 0. 007,0. 008, 0. 000, respectively) . The results of multiple factors regression analysis showed that age, gender,lactic acid, D-Dime, albumin, CRP, APACHE Ⅱ score, and GCS score were not the independent risk factors of prognosis of gerontal patients with SIRS ( the P = 0. 401, 0. 165, 0. 446, 0. 841,0. 615, 0. 120,0. 502, 0. 184, respectively) except ChE ( P = 0. 000) . The receiver operating characteristic curve (ROC) of ChE in the gerontal patients with SIRS showed the area under curve (AUC) = 0.797, SE =0.04, P=0. 000, and the ChE = 103.00 U/L could be a diagnosis point with sensitivity = 0.793, 1-specificity = 0. 258. The correlation analysis showed that the APACHE Ⅱ score, CRP, and albumin were poorly correlated with ChE ( Kendall coefficients were 0. 061, 0. 231, and -0. 090, and theP = 0. 161,0. 000, and 0. 069, respectively ) . Conclusions ChE maybe played a important role in the gerontal patients with SIRS, and could be a predictive index for the prognosis of gerontal patients with systemic inflammatory response syndrome.

Objective To provide insight into the clinical manifestation,histopathology characteristics,diagnostic and therapeutic methods of primary histiocytic sarcoma (HS) of central nervous system.Methods The clinical,auxiliary examination and pathological data of one patient with intracranial primary histiocytic sarcoma were presented,and relevant literature were reviewed.Results A 55-year-old female had an 2-month history of hypomnesia and unsteady gait.MRI scans showed multiple mass lesions in brain.Biopsies of the brain lesion showed the tumor cells had polymorphism,and abundant cytoplasm was eosinophilic or clear,with large,pleomorphic nuclei.Immunohistochemically,the tumor cells stained positively with CD45,CD68,CD163,Ki67 and Vimentin,but negatively with pan-cytokeratin,epithelial membrane antigen,CD3,CD20,CD79 a,estrogen receptor,progesterone receptor,Melan-A and glial fibrillary acidic protein.Though she had received radiotherapy,the disease progressed and her consciousness deteriorated within 2 months.Conclusions HS should be considered if multiple or single intracranial unexplained lumps are found and the earliest pathological biopsy is required for early diagnosis.There are no effective therapeutic methods for HS and the prognosis is very poor.

ObjectiveTo explore the relationship between sleep quality and glucose level,diabetic complications in elderly type 2 diabetes mellitus.Methods A total of 130 hospitalized elderly type 2 diabetes in our hospital were included in the study. Questionnaires and other related clinical data were collected within one week after admission.Patients were divided into two groups:poor-sleeper group and good-sleeper group according to Pittsburgh Sleep Quality Index(PSQI).ResultsSixty percent (78/130) of these patients were poor sleepers. The following parameters differed in the two groups:the duration of diabetes [ (7.9 ± 1.8 ) years vs ( 7.2 ± 1.5 ) years,t =2.318 ],systolic blood pressure [ ( 148 ± 30 ) mm Hg ( 1 mm Hg =0.133 kPa) vs ( 138 ± 23 ) mm Hg,t =2.037 ],fasting plasma glucose (FPG) [ ( 10.7 ± 2.2) mmol/Lvs ( 9.8±1.9)mmol/L,t =2.410],hemoglobin A1c (HbA1c) [(8.6 ±2.2)％ vs (7.8±2.1 ) ％,t =2.068],high-sensitive C-reactive protein (hs-CRP) [ (5.27 ± 2.34) mg/L vs (4.44 ± 1.76)mg/L,t =2.179 ],ratio of diabetic complications ( 61％ vs 32％,x2 ＝ 4.257 ),percentage of depression ( 20％ vs 8％,x2 =3.722 ),score of life quality [ ( 98 ± 19 ) scores vs ( 89 ± 13 ) scores,t ＝ 2.980 ],and proportion of patients treated with insulin (32％ vs 12％,x2 =4.489). All the above parameters were significantly higher in poor-sleeper group than the good-sleeper group (all P value＜ 0.05 ). Multiple correlation analysis showed that the factors affecting sleep quality were FPG,HbA1c,duration of diabetes,diabetic complications,depression,life quality and insulin application (r =0.213,0.257,0.223,0.335,0.422,0.3451,0.231,respectively ; all P value ＜ 0.05 ).By multivariate logistic regression analysis,the followings were found:FPG (β =1.29,P ＜ 0.05 ) and PSQI (β =1.07,P ＜ 0.05 ) were found to be correlated with HbA1c.With increasing of PSQI,FPG,HbA1c,diabetic complications and life quality were changed significantly( all P value ＜ 0.05 ).The indcpcndcnt risk factors of diabetic complications were duration of diabetes ( OR ＝ 1.32,95％ CI 1.01-2.01 ),HbA1c ( OR =2.01,95％ CI 1.63-2.67 ),hs-CRP( OR =1.12,95％ CI 1.08-1.21 ) and PSQI ( OR =1.71,95％ CI 1.58-2.02).ConclusionsElderly type 2 diabetes mellitus are usually poor sleepers. Sleep quality probably affects blood glucoseregulation, and is closely correlated with the occurrence of complications.In addition,poor sleep quality results in poor life quality.

OBJECTIVE To investigate the significance of Epworth sleepiness scale(ESS)and modified Epworth sleepiness scale(MESS),and evaluate the feasibility of MESS in assessment of obstructive sleep apnea hypopnea syndrome(OSAHS).METHODS The ESS and MESS of 232 patients with OSAHS was recorded in their first visiting.The scores of ESS and MESS were analyzed with the parameters of polysomnography(PSG). RESULTS Both ESS and MESS can reflect the degree of sleepiness and anoxemia in OSAHS patients,but the MESS was more efficient than ESS.The difference of MESS score between normal group and severe OSAHS group was greater than that of ESS score.CONCLUSION MESS is concerned the living habit of Chinese,and can partly reflect the station of patient with OSAHS.MESS can also be a primary screening method for suspected patients with severe OSAHS.

OBJECTIVE: To investigate the clinical effectiveness of Toubiao Qingfei (expelling exterior evil and clearing lung) Decoction (TBQFD) on wind-warm and pulmonary heat syndrome. METHODS: Forty-six subjects were randomized into treatment group and control group. Patients in the control group were treated with Western medicines, while patients in the treatment group were treated with Western medicines and TBQFD. The therapeutic effects and improvement of symptoms in both groups were observed. RESULTS: The durations of fever, cough and absorption of pulmonary inflammatory focus in the treatment group were 1.52, 3.52 and 6.25 days respectively, which were significantly shorter than those in the control group (P<0.05). CONCLUSION: TBQFD can improve the symptoms, such as fever and cough, and can promote the absorption of infection and shorten the clinical course of wind-warm and pulmonary heat syndrome.

OBJECTIVE: To explore the ways of quantitative and objective evaluation for analyzing the multiple influence factors on middle ear function in the patients with primarily diagnosed NPC, and to analyze the influence factors of middle ear function in the patients with primarily diagnosed nasopharyngeal carcinoma (NPC). METHOD: Three hundred and twenty cases (320 ears) of primarily diagnosed NPC patients were examinated with electric otoscope, acoustic immittance measurement, pure tone audiometry, nasopharynx and middle ear CT or MRI scanning, eustachian tube function examination, and electronic nasopharyngoscope. A series of quantitative methods, as the influence factors including T stage, clinical stage, location, diffusion type and form of tumor, eustachian tube function, pharynx mouth shape, imaging extension (nasal, skull base, pharyngeal recess, parapharyngeal space, tensor veli palatini muscle, levator veli palatini and so on), were used to evaluate the middle ear function. SPSS 13.0 was used to anlyze the single and multiple factors in statistics. RESULT: T stage, clinical stage, location, diffusion type, and form of tumor, pharynx mouth shape, imaging extension (nasal, skull base, pharyngeal recess, parapharyngeal space, tensor veli palatini muscle, levator veli palatini) were the single influence factors on the function of middle ear in primarily diagnosed NPC patients. The gender, age, pathological types, N staging and M staging of NPC patients primarily diagnosed had no effect on middle ear function. The multple factors analysis showed that T stage, tumor location, the function of eustachian tube, tensor veli palatini muscle invasion, and skull base invasion were independent factor of affecting the middle ear function on primarily diagnosed NPC patients. CONCLUSION In this study, the influence factors of middle ear function with primarily diagnosed NPC were related to T stage, location of tumor, the function of eustachian tube, tensor veli palatini muscle invasion, skull base invasion, otitis media and quantitative criteria. The way of quantitative analysis could be used to evaluate objectively the middle ear function in patients with primarily diagnosed NPC.
